Two Factor (2FA) Authentication via Email

By SS88 LLC

Description

A simple, lightweight, yet effective plugin to enable two factor (2FA) authentication via email.

WordPress is the world’s most popular content management system (CMS), with over 40% of all websites running on it. As such, it has become a prime target for hackers looking to exploit vulnerabilities to gain unauthorized access to websites. One of the best ways to enhance the security of a WordPress site is to enable two-factor authentication (2FA) for administrators.

  • Simply enable the plugin then edit a user account to enable 2FA for that individual user.
  • Please make sure your WordPress website sends and receives emails correctly. The best way is to use a SMTP plugin.

Screenshots

  • Under each user account settings, you can click the toggle to turn 2FA on/off.
  • When 2FA is enabled, the user will see this screen after a log-in.
  • An example of an error screen.

Installation

Use the automatic installer via WordPress or download the plugin and:

  1. Upload the plugin files to the /wp-content/plugins/two-factor-2fa-via-email directory.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress.
  3. Navigate to your profile or any other users and enable to toggle 2FA to enable per account.

FAQ

Help! I’m locked out!

If you are not receiving the email to login then in order to regain access to your account, you’ll have to disable the plugin. The only way to do this is by renaming the plugin folder from two-factor-2fa-via-email to two-factor-2fa-via-email.backup or equivalent.

15 minutes is too long/short for me. Can this be changed?

Yes! As of version 1.5.2 you can now add a defined constant to your wp-config.php file;

define('SS88_2FAVE_LINK_EXPIRES_MINUTES', 10);

Where the number 10 is, change this to whatever value (in minutes) you prefer.

Reviews

Easily gives that extra security everyone should have

After trying out some of the other plugins from this developer, I saw there was this 2FA plugin. The sheer amount of spam I get really has raised concerns about security and I'm so glad I found this. Install - click the toggle for 2FA on the user account - done. Easiest way to boost security going, no crazy configuration needs, took literally seconds to do. Seems to work perfectly and I feel a lot better about the integrity of my accounts.
