SecSign

We regret to inform you that due to low demand, we have made the difficult decision to discontinue development of our WordPress plugin. We appreciate the trust you’ve placed in us and are grateful for your continued support.
Please note that while our servers will continue to operate, supporting the SecSign App, we will no longer maintain or update the WordPress plugin. You can still use the existing version, but we won’t be releasing any further updates.
As a precaution, we recommend exploring alternative solutions to ensure compatibility with future WordPress updates, as the plugin may cease to function properly.
Unfortunately, due to the unique nature of our plugin and its integration with the SecSign App, we are unable to recommend an alternative solution that can provide the same level of functionality and security.
We apologize for any inconvenience this may cause and appreciate your understanding in this matter.
Once again, thank you for your loyalty and understanding.
Best regards,
The SecSign Team

The SecSign ID two-factor authentication WordPress Plugin will be discontinued.

Stroke Infotech

Secure WordPress login with this two factor authentication (MFA / 2FA) plugin. Users for whom it is enabled will require a one-time code in order to log in.
Features
<ul>
<li>Supports standard TOTP protocols (and so supports Google Authenticator, Authy, and many others).</li>
<li>Displays graphical QR codes for easy scanning into apps on your phone/tablet</li>
<li>MFA can be turned on or off by each user</li>
<li>Supports front-end editing of settings, via shortcode (i.e. users don’t need access to the WP dashboard).</li>

User login history
[si2flose_twofactor_user_settings]
</li>
<li>
Simplified user interface and code base for ease of use and performance
</li>
<li>Alert users if someone appears to have found out their password, as indicated by successfully entering a password but repeatedly entering an incorrect MFA code.</li>
<li>When using the front-end shortcode, require the user to enter the current MFA code correctly to be able to activate MFA</li>
</ul>
<h4>How Does MFA / 2FA Work?</h4>
This plugin uses the industry standard MFA / 2FA algorithm <a href="https://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm" rel="nofollow ugc">TOTP</a> 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.
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.
<h4>Plugin Notes</h4>
This plugin began life in early 2025 as a friendly fork and enhancement of “wp mfa authentication” plugin.
This plugin requires PHP version 5.3 or higher and support for either php-openssl or <a href="http://www.php.net/manual/en/mcrypt.installation.php" rel="nofollow ugc">PHP mcrypt</a>. The vast majority of PHP setups will have one of these. If not, ask your hosting company.
<ol>
<li>Search for ‘SI 2FA Login Security’ in the ‘Plugins’ menu in WordPress.</li>
<li>Click the ‘Install’ button. (Make sure you picks the right one)</li>
<li>Activate the plugin through the ‘Plugins’ menu in WordPress</li>
<li>Find site-wide settings in 2FA User Settings ; find your own user settings in the top-level menu entry “2FA User Settings”.</li>
</ol>
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:
<pre><code>[si2flose_twofactor_user_settings]
</code></pre>
