Last updated on April 01st, 2020 by Will Morris. Filed under WordPress Admin Tips

When you use two-factor authentication (2FA) on your WordPress website, you need the username, password, and a one-time code to login.

The one-time code can be generated by an app, sent to you over email, or generated by a third party specialized device. However, how can you still login if you not have access to the 2FA app, or the mailbox where the 2FA code was sent? Is there a fail safe backup plan?

Yes, there is. You can login with backup codes. In this article we explain what backup codes are, how you can generate them, and how you can login with them.

What are backup codes?

Backup codes are a number of one-time codes you can generate specifically for your WordPress user when you have 2FA enabled. You need the backup codes in case you want to login to your WordPress website and cannot access the primary one-time code generator.

How do you get the 2FA backup codes?
