Facebook offers two-factor authentication through authentication apps, SMS, and physical security keys. However, Facebook recommends using an authentication app, such as Google Authenticator or Duo Mobile, both of which randomly generate authentication codes each time you use the app. Here are the steps to set up two-factor authentication for your Facebook account using an authentication app:
- Open the Facebook app on your phone.
- Go to Settings & privacy – the icon looks like a cog and is in the top right-hand corner of the Facebook app.
- In this menu, go to Password and security listed under Account settings.
- Scroll down this menu to Two-factor authentication.
- Select a two-factor authentication security method – authenticator app or text message (SMS) .
- Youll be asked to set up the third-party authenticator which, if you dont already have it installed, you can download from several sources. If the Facebook app is on the same phone as your authenticator app, tap Set up on same device, which will save the key to the app. You can also save the key by copying the code and manually entering it into the authenticator app.
- Confirm the prompt to save the key.
Once you have set up two-factor authentication, you will need to enter a verification code from your authentication app each time you log in to your Facebook account.
