Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) or Two-Step Verification is an additional layer of security you add to your WordPress login page. With 2FA it is nearlly impossible for attackers to hijack your WordPress user, even if they guess the password.

As a benefit the two-factor authentication is in a way good to help mitigate WordPress brute force attacks.

An out of the box install of WordPress does not have 2FA.
You need a third party plugin to enable it on your website.
