WordPress has always had a robust library. However, this means fiddling with the not-so-awesome plugins. That’s why we are here. We will list only the best so that you don’t have to waste time finding them. So, without any delay, let’s get started.

Two Factor Authentication is a relatively new plugin. It is created by the author of the popular UpdraftPlus plugin.

Just like any other two-factor authentication plugin, once activated, the user needs to use the one-time code whenever he logs in. Two-factor authentication comes with a lot of features including the support of HOTP and TOTP protocols. This means that it also supports Authy, Google Authenticator and other authenticators out there.

Other key features include the following:

  • It can be turned on and off per user.
  • It can be made accessible on a per-role basis. This means that it can be made available for admins and turned off for subscribers.
  • It is WP Multisite compatible
  • Supports emergency code [Premium version only]

3. Open ID

Open ID is an interesting concept that lets users authenticate websites without even creating a new password. Generally, two-way authentication works with a password and a one-time code generated every time you want to log in. In this case, the account created in using OpenID doesn’t need one. This makes it easy for users to access the WordPress website, comment using multiple accounts with just one click and so on.

Open ID has a much bigger ecosystem as it enables users to use their OpenID on other websites as well. The site only needs to have OpenID support.

4. SecSign


SecSign works similar to OpenID. By using SecSign you don’t need to use your password. All you need is a smartphone to log in. Two-factor authentication comes differently. Let’s try to understand it. The first-factor authentication comes from having a mobile device with the SecSign app. The second-factor authentication is the code generated by the app to log in. You can also choose to use biometric identification that is baked directly into the app.

Using SecSign is liberating as it doesn’t need you to type the password every time you want to log in. All you need to do is the type of your ID in a SecSign powered WordPress website.
