How to Turn on Two-Factor Authentication on Facebook

Keep your Facebook account secure with 2FA

Facebook accounts often contain a great deal of personal information and other private data, so having someone access your FB account without permission could be a devastating experience. Having a complex password is no longer enough to ensure your account remains safe, so it's important to know how to activate two-factor authentication (2FA) on Facebook. It adds a level of security to the login process and helps protect your private information from being exposed to prying eyes.

How to Activate Two-Factor Authentication on Facebook

With 2FA enabled you’ll be asked to validate your identity each time you log in. Validation uses one of several methods, which includes entering a one-time code sent to your mobile device or approving the authentication attempt on another trusted device.

  1. Go to your Facebook home page and click the down-arrow in the upper-right corner.

    For text messages, you can use a phone number already associated with your Facebook account, or choose a new one to receive these texts. 

  8. Select a backup method. You have the option of using a static recovery code only you know or tapping the security key (i.e., Touch ID) on a compatible device.

    These backup methods are not mandatory but are recommended in case you cannot access your primary 2FA device or application. To configure either, select Setup next to the Security Key and/or Recovery Codes options. 

  9. When 2FA is first enabled, you’ll be asked if you want to save the computer, smartphone, or tablet you're currently logging in from. If you opt to do this, you won’t be required to enter a security code every time you access Facebook from the device in question.

This should never be done on public computers or other devices used by other people.
