14
15 == Description ==
16
17 Secure WordPress login with this two factor authentication (TFA / 2FA) plugin. Users for whom it is enabled will require a one-time code in order to log in. From the authors of <a href="https://updraftplus.com/">UpdraftPlus - WP's #1 backup/restore plugin</a>, with over two million active installs.
18
19 Are you completely new to TFA? <a href="https://wordpress.org/plugins/two-factor-authentication/faq/">If so, please see our FAQ</a>.
20
21 Features (please see the "Screenshots" for more information):
22
23 * Supports standard TOTP + HOTP protocols (and so supports Google Authenticator, Authy, and many others).
24 * Displays graphical QR codes for easy scanning into apps on your phone/tablet
25 * TFA can be made available on a per-role basis (e.g. available for admins, but not for subscribers)
26 * TFA can be turned on or off by each user
27 * TFA can be required for specified user levels, after a defined time period (e.g. require all admins to have TFA, once their accounts are a week old) (<a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a>), including forcing them to immediately set up (by redirecting them to the page to do so)
28 * Supports front-end editing of settings, via [twofactor_user_settings] shortcode (i.e. users don't need access to the WP dashboard). (The <a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a> allows custom designing of any layout you wish).
29 * Site owners can allow "trusted devices" on which TFA codes are only asked for a chosen number of days (instead of every login); e.g. 30 days (<a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a>)
30 * Works together with <a href="https://wordpress.org/plugins/theme-my-login/">"Theme My Login"</a> (both forms and widgets)
31 * Includes support for the WooCommerce and Affiliates-WP login forms
32 * Includes support for Elementor Pro login forms (Premium version)
33 * Includes support for bbPress login forms (Premium version)
34 * Includes support for any and every third-party login form (Premium version) without any further coding needed via appending your TFA code to the end of your password
35 * Does not mention or request second factor until the user has been identified as one with TFA enabled (i.e. nothing is shown to users who do not have it enabled)
36 * WP Multisite compatible (plugin should be network activated)
37 * Simplified user interface and code base for ease of use and performance
38 * Added a number of extra security checks to the original forked code
39 * Emergency codes for when you lose your phone/tablet (<a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a>)
40 * When using the front-end shortcode (<a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a>), require the user to enter the current TFA code correctly to be able to activate TFA
41 * Works together with <a href="https://wordpress.org/plugins/wp-members/">"WP Members"</a> (shortcode form)
42 * Administrators can access other users' codes, and turn them on/off when needed (<a href="https://www.simbahosting.co.uk/s3/product/two-factor-authentication/">Premium version</a>)

44 = Why use TFA / 2FA ? =
45
46 Read this! <a href="https://www.wired.com/2012/08/apple-amazon-mat-honan-hacking/">https://www.wired.com/2012/08/apple-amazon-mat-honan-hacking/</a>
47
48 = How Does TFA / 2FA Work? =
49
50 This plugin uses the industry standard TFA / 2FA algorithm [TOTP](https://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm) or [HOTP](https://en.wikipedia.org/wiki/HMAC-based_One-time_Password_Algorithm) for creating One Time Passwords. These are used by Google Authenticator, Authy, and many other OTP applications that you can deploy on your phone etc.
51
52 A TOTP code is valid for a certain time. Whatever program you use (i.e. Google Authenticator, etc.) will show a different code every so often.
53
54 = Plugin Notes =
55
56 This plugin began life in early 2015 as a friendly fork and enhancement of <a href="https://wordpress.org/plugins/two-factor-auth/">Oscar Hane's "two factor auth" plugin</a>.
57
58 == Installation ==
59
60 This plugin requires PHP version 5.3 or higher and support for either php-openssl or [PHP mcrypt](http://www.php.net/manual/en/mcrypt.installation.php). The vast majority of PHP setups will have one of these. If not, ask your hosting company.
61
62 1. Search for 'Two Factor Authentication' in the 'Plugins' menu in WordPress.
63 2. Click the 'Install' button. (Make sure you picks the right one)
64 3. Activate the plugin through the 'Plugins' menu in WordPress
65 4. Find site-wide settings in Settings -> Two Factor Authentication ; find your own user settings in the top-level menu entry "Two Factor Auth".
66
67 If you want to add a section to the front-end of your site where users can configure their two-factor authentication settings, use this shortcode: [twofactor_user_settings]
68
69 == Frequently Asked Questions ==
70
71 = What is two factor authentication (TFA / 2FA) ? =
72
73 Basically, it's to do with securing your logins, so that there's more than one link in the chain needing to be broken before an unwanted intruder can get in your website.
74
75 By default, your WordPress accounts are protected by only one thing: your password. If that's broken, then everything's wide open.
76
77 "Two factor" means adding a second requirement. Usually, this is a code that comes to a device you own (e.g. phone, tablet) - so, someone can't get into your website without getting hold of your device. <a href="https://en.wikipedia.org/wiki/Two_factor_authentication">You can get a longer answer from Wikipedia.</a>
78
79 Sometimes it is also called multi-factor authentication instead of two-factor - because someone could secure their systems with as many factors as they like.
80
81 = Why should I care? =
82
83 Read this: <a href="https://www.wired.com/2012/08/apple-amazon-mat-honan-hacking/">https://www.wired.com/2012/08/apple-amazon-mat-honan-hacking/</a>
84
85 = How does two factor authentication (TFA / 2FA) work? =
86
87 Since "two factor authentication" just means "a second something is necessary to get in", this answer depends upon the particular set-up. In the most common case, a numeric code is shown on your phone, tablet or other device. This code be sent via an SMS; this then depends on the mobile phone network working. This plugin does not uses that method. Instead, it uses a standard mathematical algorithm to generate codes that are only valid once each, or for only for 30 seconds (depending on which algorithm you choose). Your phone or tablet can know the code after it has been set up once (often, by just scanning a bar-code off the screen).
88
89 = What do I need to set up on my phone/tablet (etc.) in order to generate the codes? =
90
91 This depends on your particular make of phone, and your preferences. Google have produced a popular app called "Google Authenticator", which is a preferred option for many people because it is easy to use and can be set up via just scanning a bar code off your screen - <a href="https://support.google.com/accounts/answer/1066447"> follow this link, and ignore the first paragraph that is talking about 2FA on your Google account</a> (rather than being relevant to this plugin).
92
93 = What if I do not have a phone or tablet? =
94
95 Many and various devices and programs can generate the codes. One option is an add-on for your web browser; for example, <a href="https://chrome.google.com/webstore/search/authenticator">here are some apps and add-ons for Google Chrome</a>. Wikipedia <a href="https://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm#Client_implementations">lists various programs for different computers</a>.
96
97 = I lost my device that has pass-codes - or, they don't work. What to do? =
98
99 If your pass-code used to work, but no longer does, then check that the time on your device that generates them is accurate.
100
101 If you cannot get in and need to disable two-factor authentication, then add this to your wp-config.php file, using FTP or the file manager in your hosting control panel:
102
103 <code>define('TWO_FACTOR_DISABLE', true);</code>
104
105 Add it next to where any other line beginning with "define" is.
106
107 Alternatively, if you have FTP or cPanel access to your web hosting space, you can de-activate the plugin; <a href="https://updraftplus.com/understanding-wordpress-installs-plugins/">see this article.</a>
108
109 = Why does the plugin not support sending the two-factor code by email? =
110
111 If someone has access to your email account, then they can send a password-reset code there using the password-reset mechanisms built into WordPress. Therefore, if the two-factor code was also sent there, then ability to read your email allows the breaking of both factors, and hence is no longer truly *two* factor authentication.
112
113 Some users might have two factor authentication on their email account, but this is not knowable or controllable from inside WordPress, and so giving this option to users means that the administrator cannot see or enforce two-factor authentication. And even in this case, email is often sent between servers unencrypted, and so is susceptible to man-in-the-middle attacks beyond the control of WordPress.
114
115 = What are HOTP and TOTP? =
116
117 These are the names of the two mathematical algorithms that are used to create the special codes. These are industry-standard algorithms, devised by expert cryptographers. HOTP is less popular, but the device that generates the codes does not need to know the correct time (instead, the codes are generated in a precise sequence). TOTP is much more popular, and generates codes that are only valid for 30 seconds (and so your device needs to know the time). I'd recommend TOTP, as HOTP can be annoying if something causes the sequences to get out of sync.
118
119 = What is the shortcode to use for front-end settings? =
120
121 [twofactor_user_settings]
122
123 = I deliberately entered a wrong password, and it let me login! =
124
125 You have a password manager extension installed in your web browser, with the correct password entered in it. It has automatically replaced your wrong password with the right one from its saved store. This behaviour has been observed and confirmed by several users. You can verify it by using the web developer tools in your browser to look at the HTTP data sent to WordPress, and observe which password is actually in it. You can also open a fresh web browser with no such extension in it to re-test.
126
127 Note that the two factor authentication plugin has no mechanism to compare or approve passwords; this is done by WordPress core. If the wrong password is sent, then this is handled by WordPress, and the login will not proceed.

365 * TWEAK: Update updater class to 1.8 series
366
367 = 1.6.1 - 10/Aug/2019 =
368
369 * TWEAK: Response to an attempt to turn TFA on can now include an "error" attribute if the attempt failed due to failure to supply the current code
370
371 = 1.6.0 - 08/Aug/2019 =
372
373 * FEATURE: (Premium version) By using the parameter style="require_current" with the shortcode twofactor_user_settings_enabled, the user will only be able to activate TFA if they enter the current TFA code
374 * TWEAK: Remove the incorrect suffix "(Premium)" (double-suffix in the actual Premium version) that appeared in the plugin title in 1.5.6
375
376 = 1.5.6 - 06/Aug/2019 =
377
378 * TWEAK: Allow customisation of a particular message via a filter simbatfa_message_you_should_verify
379 * TWEAK: Replace "eachother" with "each other"
380
381 = 1.5.5 - 30/Jul/2019 =
382
383 * TWEAK: Force a global context when creating the initial Simba_Two_Factor_Authentication object, to work around direct accesses from components that do not set the scope correctly
384
385 = 1.5.4 - 17/Jul/2019 =
386
387 * FEATURE: (Premium version) - allow the site administrator to forbid users who have compulsory TFA to turn it off (supplementing the additional capability to prevent them logging in)
388
389 = 1.5.3 - 22/Jun/2019 =
390
391 * TWEAK: When using your final emergency code (Premium version), and viewing your settings (which regenerated new ones), then if you did not follow the advice to reset your prviate key, you would get the same codes as before. This might be thought undesirable (though is not a security flaw, as the emergency codes are no more guessable the second time around than the first). This behaviour has now been changed.
392
393 = 1.5.2 - 08/Jun/2019 =
394
395 * TWEAK: When php-mcrypt was not installed, pressing the "Reset private key" link in a user's settings would cause an unnecessary PHP notice, and display a wrong "current code" for a few seconds.
396
397 = 1.5.1 - 05/May/2019 =
398
399 * FEATURE: Support any login form (Premium version) via appending the TFA code onto the end of the password. This allows support even of login forms coded in a way that make integrations (that aren't hacks or inordinate amounts of work-around code) impossible (e.g. PeepSo)
400 * TWEAK: Minor wording tweak in the explanation of how TOTP works.
401
402 = 1.4.12 - 18/Apr/2019 =
403
404 * TWEAK: Add a filter simba_tfa_localisation_strings allowing further customisation of front-end strings
405 * TWEAK: Add an extra instructional message in the "Make two factor authentication compulsory" section (Premium) to explain how to cope with existing users
406 * TWEAK: Cope with the user entering spaces in their two-factor code (TOTP protocol codes are numbers only, but some apps apparently display formatting and users are not aware)
407 * TWEAK: Mark as supporting WP 5.2
408
409 = 1.4.11 - 08/Mar/2019 =
410
411 * FIX: On multisites, the user search should search on all sites, not just the main one
412
413 = 1.4.10 - 01/Mar/2019 =
414
415 * TWEAK: Introduce a filter, simba_tfa_management_capability, allowing the WP capability (default: manage_options) required by a user to manage the plugin to be changed. (Be careful - giving the ability to manage could potentially mean the ability to lock any user out).
416
417 = 1.4.9 - 20/Feb/2019 =
418
419 * SECURITY: The security fix in version 1.4.7 was faulty and failed to completely fix the problem; it is now resolved in this release. Our apologies for the double update.
420
421 = 1.4.8 - 16/Feb/2019 =
422
423 * FIX: On some multisite setups, the link to the site-wide administration settings went to the wrong place
424
425 = 1.4.7 - 06/Feb/2019 =
426
427 * SECURITY: If a user's WordPress account username was in the form of an email address, and if their actual account email address was something different, and TFA was set up on that account, and used the "username" (that looked like an email address) to login, then TFA controls upon login on that account would be ineffective. Other accounts were not affected (regardless of whether you login by email or not). This vulnerability was inherited from the original "Two Factor Auth" plugin that this plugin was forked from, and so is present in all versions before this one.
428
429 = 1.4.6 - 05/Feb/2019 =
430
431 * FIX: When displaying a user's trusted devices in the admin page, the time that a device was trusted until was not shown correctly (instead, it showed the current time)
432 * FIX: Removing the first trusted device in a list did not always work
433 * TWEAK: Display "(none)" when there are no trusted devices
434
435 = 1.4.4 - 04/Feb/2019 =
436
437 * FEATURE: Trusted devices are now listed in the user's admin page, allowing them to see and remove trust from their devices.
438 * TWEAK: Updated .pot file
439
440 = 1.4.3 - 28/Jan/2019 =
441
442 * FIX: The "Trusted devices" functionality (Premium) checkbox was not appearing when activated
443 * TWEAK: Add a missing translation domain to a phrase
444
445 = 1.4.1 - 25/Jan/2019 =
446
447 * FEATURE: Trusted devices: A site owner can now choose to allow particular user levels (e.g. admins, editors) to mark devices as 'trusted' and thereby exempt from needing to enter a TFA code for a chosen number of days. This feature is off by default and requires https (i.e. SSL) on the login form and cookies to be kept in the trusted device.
448 * FIX: Fix a regression in 1.4.0 whereby when a site owner viewed another user's current code, it could later self-update with the wrong user's value
449 * TWEAK: Add the robustness in parsing broken JSON present on the standard WP login form to other login forms
450 * TWEAK: Various internal code documentation improvements
451 * TWEAK: Suppress mcrypt deprecation notices in places where we would use an alternative if it was not present
452 * TWEAK: Bumped the support requirement up to WP 3.4. I'm not aware of anything done to break it on 3.3, but this is the official requirement (it's very hard to test old WP versions as they don't run on modern webserver stacks)
453
454 = 1.4.0 - 24/Jan/2019 =
455
456 * FEATURE: Where the current OTP code is displayed (during setup), this will now self-update automatically (i.e. without needing a manual press on the "update" link).
457 * TWEAK: Various improvements to the layout and text of the setup page to help make the process more understandable
458 * TWEAK: The current code is shown next to the UI option for enabling TFA
459 * TWEAK: Prevent a PHP notice if AUTH_KEY was not defined (on some very old WP installs)
460
461 = 1.3.13 - 18/Dec/2018 =
462
463 * SECURITY: Fix a logged-in CSRF vulnerability reported by Martijn Korse (www.bitnesswise.com). Due to a missing nonce check, if an attacker was able to persuade a personally-targetted victim who was currently logged in to their WordPress account to visit a personally-crafted (for the individual victim) page in the same browser session, then the attacker would be able to de-activate two-factor authentication for the victim on that WordPress site (thus leaving the targetted account protected by the user's password, but not by a second factor - the absence of a request for a TFA code would be apparent on the user's next login). This vulnerability was inherited from the original "Two Factor Auth" plugin that this plugin was forked from, and so is present in all versions before this one.
464 * TWEAK: Some minor code-tidying
465 * TWEAK: Update bundled Premium updater library to current version (1.5.10)
466
467 = 1.3.12 - 14/Dec/2018 =
468
469 * TWEAK: Prevent a PHP debugging notice when $pagenow is not set
470
471 = 1.3.11 - 04/Dec/2018 =
472
473 * FEATURE: Add a 'TFA' column on the Users screen in the WP admin dashboard to display TFA status, thanks to Enrico Sorcinelli.
474
475 = 1.3.10 - 30/Nov/2018 =
476
477 * FIX: TFA codes were not being requested on the login form on a WooCommerce dedicated order payment page (i.e. /checkout/order-pay/123456/?pay_for_order=true&key=wc_order_blahblahblah) (meaning that if a user had TFA activated, login would fail).
478 * TWEAK: Prevent a PHP notice if AUTH_SALT was not defined (on some very old WP installs)
479
480 = 1.3.9 - 30/Oct/2018 =
481
482 * SECURITY: If you were not using the recommended option of requiring 2FA for XMLRPC requests, then an attacker could potentially also bypass requirements for 2FA on ordinary logins (i.e. only need the password). Such users will want to immediately update, though we recommend that all users do. This vulnerability was inherited from the original "Two Factor Auth" plugin that this plugin was forked from, and so is present in all versions before this one.
483
484 = 1.3.8 - 25/Oct/2018 =
485
486 * TWEAK: Update the updater class in the Premium version to the current release (1.5.6)
487
488 = 1.3.7 - 15/Oct/2018 =
489
490 * TWEAK: Try to mitigate plugins on the login page which cause JavaScript exceptions by enqueing our scripts earlier.
491
492 = 1.3.6 - 04/Oct/2018 =
493
494 * TWEAK: Add attribute autocomplete="off" on the WooCommerce login form TFA field (was already present for regular WP login form)
495 * TRANSLATION: Added Portuguese (Brazilian) translation, courtesy of Dino Marchiori
496
497 = 1.3.5 - 02/Oct/2018 =
498
499 * TWEAK: Some code-styling consistency clean-ups
500 * TWEAK: Allow one more window's tolerance by default for codes from devices running fast
501
502 = 1.3.4 - 11/Sep/2018 =
503
504 * FIX: Sometimes a TML widget login form could fail to work because of a changed/unexpected DOM tree
505 * FIX: Some further breakage in TML had occurred, causing login buttons to require to be pressed twice
506
507 = 1.3.3 - 31/Jul/2018 =
508
509 * FIX: Restore support for "Theme My Login", which had been broken by unannounced changes in TML 7.x
510 * TRANSLATIONS: Update .pot file
511
512 = 1.3.2 - 31/May/2018 =
513
514 * TWEAK: Add the simbatfa_check_tfa_requirements_ajax_response and simbatfa_verify_code_and_user_result filters to allow over-riding of the response to the "TFA required?" question and the TFA check itself by developers
515
516 = 1.3.1 - 25/May/2018 =
517
518 * FIX: The WooCommerce 3.3+ login form was requiring two clicks on the 'Log In' button
519 * TWEAK: The progress spinner had disappeared on WooCommerce 3.3+
520
521 = 1.3.0 - 05/Apr/2018 =
522
523 * FEATURE: (Premium version) Integration with the WP-Members login form, https://wordpress.org/plugins/wp-members/ . N.B. WP-Members does not pass on the real error message upon a login failure, but displays its own hard-coded message that the username/password were wrong; so you'll see this even if it was really the TFA code that was wrong.
524 * TWEAK: Change the permission check for editing other users (Premium version) to edit_users (instead of the previous update_plugins, intended just as a proxy for "is an admin")
525 * TWEAK: Stop using the deprecated jQuery.parseJSON method
526 * TWEAK: Change a string that was not in a translatable form
527 * TWEAK: Update the updater class in the Premium version to the current release (1.5.1)
528
529 = 1.2.35 - 28/Nov/2017 =
530
531 * TWEAK: Upon front-end settings save, do jQuery(document).trigger('tfa_settings_saved'), allowing the user to respond to the action (e.g. reload page)
532 * TWEAK: Suppress mcrypt deprecation notices on PHP 7.1 (we already know it is deprecated, and already use openssl if it is not installed)
533
534 = 1.2.34 - 08/Nov/2017 =
535
536 * TWEAK: Remove calls to the deprecated screen_icon() function
537 * TWEAK: Remove some unnecessary bundled translation files
538 * TWEAK: Add some translation files not previously included in the Premium version
539 * TWEAK: Update bundled Premium updater library to current (1.5.0)
540
541 = 1.2.33 - 09/Oct/2017 =
542
543 * FIX: The available/required settings for super-admins on multisite installs were not saving (Premium feature)
544 * FIX: When the admin fetched another user's current QR code, it embedded the wrong username (which was a cosmetic issue only - the code itself was correct) (Premium feature)
545
546 = 1.2.32 - 06/Oct/2017 =
547
548 * TWEAK: Update bundled updater in Premium to latest version (1.4.8)
549
550 = 1.2.31 - 05/Oct/2017 =
551
552 * FEATURE: (Relevant to Premium version): Automatically generate new emergency codes when they run out, including upon view of settings if there are none (e.g. on upgrade from free to Premium)
553 * TWEAK: Code-styling consistency tweaks
554
555 = 1.2.30 - 18/Sep/2017 =
556
557 * FIX: TML shortcode forms were not working properly for non-TFA users
558
559 = 1.2.29 - 16/Sep/2017 =
560
561 * FIX: Prevent double-show of TFA field on TML default login page (regression)
562 * FIX: Restore functionality on TML shortcode forms (regression, likely due to changes in TML)
563 * TWEAK: Restore the spinner to proper size on all forms
564 * TWEAK: A few very minor code style clean-ups
565
566 = 1.2.27 - 29/Aug/2017 =
567
568 * TWEAK: Add the new 'PHP Requires' header to readme.txt
569 * TWEAK: Correct a couple of wrong translation domain references
570
571 = 1.2.26 - 08/Aug/2017 =
572
573 * FIX: Do not request TFA code on TML reset password form (regression, likely due to changes in TML)
574 * APOLOGIES: 1.2.25 was a faulty release that would block logins. You should immediately update.
575
576 = 1.2.24 - 05/Aug/2017 =
577
578 * TWEAK: Update to the latest version of the updater library (Premium)
579
580 = 1.2.23 - 15/Jun/2017 =
581
582 * TWEAK: Allow admins to reset users' private keys (Premium)
583
584 = 1.2.22 - 23/May/2017 =
585
586 * TWEAK: Update updater library to current version (Premium)
587 * TWEAK: Use higher-quality spinner image
588 * COMPATIBILITY: Mark as compatible with WP 4.8
589
590 = 1.2.21 - 22/Feb/2017 =
591
592 * TWEAK: Update jquery-qrcode library to latest release (0.14.0)
593 * TWEAK: Explicitly encode spaces in WordPress usernames (apparently resolves a problem with a particular iPhone app)
594
595 = 1.2.20 - 17/Feb/2017 =
596
597 * TWEAK: Work around a bug seen with strlen() on one particular PHP install
598 * FIX: The line purporting to show the current UTC time was in fact taking your WordPress timezone into account. It has now been adjusted to show both to avoid ambiguity.
599 * FIX: 1.2.18 used a PHP 5.4+ only function, whereas we support PHP 5.3+
600
601 = 1.2.17 - 09/Feb/2017 =
602
603 * FIX: Fix support for login widgets from Theme My Login
604
605 = 1.2.16 - 30/Jan/2016 =
606
607 * FIX: Fix issue whereby if you were already logged in and managed to visit a login form, you would not be asked for a TFA code
608
609 = 1.2.15 - 23/Jan/2017 =
610
611 * FEATURE: Add support for login widgets from Theme My Login
612 * UPDATER: (Premium version): update to the latest updater class, including the new ability to automatically update
613
614 = 1.2.14 - 02/Jan/2017 =
615
616 * TWEAK: Add missing internationalisation headers to the main plugin file
617
618 = 1.2.13 - 31/Aug/2016 =
619
620 * TWEAK: Internationalisation implementation was not previously compatible with wordpress.org's translation system
621
622 = 1.2.12 - 20/May/2016 =
623
624 * FEATURE: Compatibility with https://wordpress.org/plugins/use-administrator-password/ - when TFA is enabled on an account, the TFA credentials of the user whose password was supplied are allowed (and required)
625
626 = 1.2.11 - 18/May/2016 =
627
628 * TWEAK: Update bundled select2 to version 4.0.2
629 * FIX: If the [twofactor_user_qrcode] shortcode (Premium version) was used without other short-codes, then the code would not display
630
631 = 1.2.10 - 31/Mar/2016 =
632
633 * TWEAK: Prefer openssl, if present, to the deprecated mcrypt. Note that if you migrate a site from a server without openssl to a server without mcrypt, then because of mcrypt's non-compliant padding, you will need to either install php-mcrypt on the new server, or disable TFA (via define('TWO_FACTOR_DISABLE', true); in your wp-config.php) to allow users to be able to log in. This also applies if the source site did have openssl, but for users who hadn't logged in since installing this update.
634 * TWEAK: Make the $simba_two_factor_authentication_premium object globally available
635 * COMPATIBILITY: Mark as tested on WP 4.5
636
637 = 1.2.8 - 12/Dec/2015 =
638
639 * FEATURE: Add support for the Affiliates-WP login form
640 * TWEAK: Defeat WooCommerce loading an old version of the select2 script onto the TFA settings page, and breaking the user selector (should work this time)
641
642 = 1.2.6 - 11/Nov/2015 =
643
644 * TWEAK: Defeat WooCommerce loading an old version of the select2 script onto the TFA settings page, and breaking the user selector
645 * TWEAK: Tested on WordPress 4.4
646 * TWEAK: Use h1 for heading style on admin page, not h2
647 * FIX: The "You'll need to use TFA to login in future" link for users for whom TFA is compulsory (Premium) was to the wrong page
648
649 = 1.2.4 - 09/Nov/2015 =
650
651 * TWEAK: Make window settings filterable
652
653 = 1.2.3 - 19/Oct/2015 =
654
655 * FIX: Fix bug in 1.2.2 that could lock out users without TFA settings
656
657 = 1.2.2 - 16/Oct/2015 =
658
659 * TWEAK: Display dashboard notice if TWO_FACTOR_DISABLE is defined in wp-config.php, to prevent time wasted wondering why nothing is happening
660
661 = 1.2.1 - 08/Oct/2015 =
662
663 * FEATURE: (Premium version) - Require users (of configured roles) to use TFA (optionally after a configurable amount of time)
664
665 = 1.1.21 - 25/Aug/2015 =
666
667 * TRANSLATIONS: Translation files can now be used (translators welcome!)
668 * TRANSLATION: Swedish translation added, courtesy of Bo Sving
669
670 = 1.1.19 - 20/Aug/2015 =
671
672 * TWEAK: Remove a pointless nonce check
673
674 = 1.1.18 - 01/Aug/2015 =
675
676 * COMPATIBILITY: Tested with WP 4.3 (RC1) and WooCommerce 2.4 (RC1) - no issues found (i.e. previous releases believed to be already compatible)
677 * FIX: When the admin is showing codes for other users, QR codes were not displaying correctly since 1.1.13
678
679 = 1.1.17 - 22/May/2015 =
680
681 * TWEAK: Introduce convenience method for developers wanting to verify that TFA is active (Premium)
682 * FIX: Fix operation of [twofactor_conditional] shortcode (Premium)
683 * FIX: Fix fatal error introduced in convenience method in 1.1.16
684
685 = 1.1.15 - 13/May/2015 =
686
687 * FIX: Fix conflict with 'reset password' form with "Theme My Login" plugin
688
689 = 1.1.14 - 12/May/2015 =
690
691 * FIX: Add TFA support to the WooCommerce login-on-checkout form (previously, TFA-enabled users could not log in using it)
692
693 = 1.1.13 - 11/May/2015 =
694
695 * TWEAK: Use jquery-qrcode to generate QR codes, replacing external dependency on Google
696 * TWEAK: Update bundled select2 library to 4.0.0 release (was rc2)
697
698 = 1.1.12 - 22/Apr/2015 =
699
700 * FIX: Fix corner-case where the user's login looked like an email address, but wasn't the account address. In this case, a OTP password was always requested.
701 * FIX: When the username does not exist, front-end should not request TFA code.
702
703 = 1.1.11 - 21/Apr/2015 =
704
705 * TWEAK: Prevent PHP notice if combining with bbPress
706 * TWEAK: Added more console logging if TFA AJAX request fails
707 * TWEAK: Add some measures to overcome extraneous PHP output breaking the AJAX conversation (e.g. when using strict debugging)
708
709 = 1.1.10 - 20/Apr/2015 =
710
711 * SECURITY: Fix possible non-persistent XSS issue in admin area (https://blog.sucuri.net/2015/04/security-advisory-xss-vulnerability-affecting-multiple-wordpress-plugins.html)
712 * FIX: Don't get involved on "lost password" forms (intermittent issue with "Theme My Login")
713
714 = 1.1.9 - 15/Apr/2015 =
715
716 * TESTING: Tested with "Theme My Login" - http://wordpress.org/plugins/theme-my-login/ - no issues
717 * TWEAK: Do a little bit of status logging to the browser's developer console on login forms, to help debugging any issues
718 * TWEAK: Add a spinner on login forms whilst TFA status is being checked (WP 3.8+)
719 * TWEAK: Make sure that scripts are versionned, to prevent updates not being immediately effective
720 * TWEAK: Make sure OTP field on WooCommerce login form receives focus automatically
721
722 = 1.1.8 - 14/Apr/2015 =
723
724 * FIX: Fix an issue on sites that forced SSL access to admin area, but not to front-end, whereby AJAX functions could fail (e.g. showing latest code)
725 * FIX: Version number was not shown correctly in admin screen since 1.1.5
726 * TWEAK: Show proper plugin URI
727
728 = 1.1.7 - 10/Apr/2015 =
729
730 * FIX: Fix plugin compatibility with PHP 5.6
731 * FIX: TFA was always made active on XMLRPC, even when the user turned it off
732
733 = 1.1.6 - 09/Apr/2015 =
734
735 * TWEAK: Change various wordings to make things clearer for new-comers to two-factor authentication.
736
737 = 1.1.5 - 07/Apr/2015 =
738
739 * FEATURE: Admin users (Premium version) can show codes belonging to other users, and activate or de-activate TFA for other users.
740 * PREMIUM: Premium version has now been released: https://www.simbahosting.co.uk/s3/product/two-factor-authentication/. Features emergency codes, personal support, and more short-codes allowing you to custom-design your own front-end page for users.
741 * TWEAK: Premium version now contains support link to the proper place (not to wordpress.org's free forum)
742 * TWEAK: Added a constant, TWO_FACTOR_DISABLE. Define this in your wp-config.php to disable all TFA requirements.
743 * FIX: Fix a bug introduced in version 1.1.2 that could prevent logins on SSL-enabled sites on the WooCommerce form when not accessed over SSL
744
745 = 1.1.3 - 04/Apr/2015 =
746
747 * TWEAK: Provide "Settings saved" notice when user's settings are saved in the admin area (otherwise the user may be wondering).
748
749 = 1.1.2 - 03/Apr/2015 =
750
751 * FIX: Include blockUI JavaScript (the lack of which caused front-end options not to save if you did not have WooCommerce or another plugin that already used blockUI installed)
752 * FEATURE: Don't show anything on the WooCommerce login form unless user is using 2FA (i.e. behave like WP login form)
753 * FEATURE: Added 9 new shortcodes for custom-designed front-end screens (Premium - forthcoming)
754
755 = 1.1.1 - 30/Mar/2015 =
756
757 * Support added for multisite installs. (Plugin should be network-activated).
758 * Support added for super-admin role (it's not a normal WP role internally, so needs custom handling)
759 * Tested + compatible on upcoming WP 4.2 (tested on Beta 3)
760 * Re-add option to require 2FA over XMLRPC (without specific code, XMLRPC clients don't/can't use 2FA - but requiring it effectively blocks hackers who want to crack your password by using this weakness in XMLRPC)
761
762 = 1.0 - 20/Mar/2015 =
763
764 * First version, forked from Oskar Hane's https://wordpress.org/plugins/two-factor-auth/
765 * Support for email "two-factor" removed (email isn't really a second factor, unless you have multiple email accounts and guard where your "lost login" emails go to)
766 * WooCommerce support added to the main plugin. Load WooCommerce JavaScript only on pages where it is needed.
767 * Use AJAX to refresh current code (rather than reloading the whole page)
768 * Added WordPress nonces and user permission checks in relevant places
769 * Shortcode twofactor_user_settings added, for front-end settings
770 * User interface simplified/de-cluttered
771
772 == Upgrade Notice ==
