How to Activate Two-Factor Authentication on Facebook
Facebook accounts often contain a great deal of personal information and other private data, so it’s important to know how to activate two-factor authentication (2FA) on Facebook. With 2FA enabled, you are asked to validate your identity each time you log in. Validation uses methods that include entering a one-time code sent to your mobile device or approving the authentication attempt on another trusted device. When 2FA is first enabled, you are 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. You shouldn’t do this on public computers or other devices used by other people. 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 or Recovery Codes option.
How to Turn Off Facebook 2-Step Verification
While this isn’t recommended, you can turn off two-factor authentication on your Facebook account by returning to Facebook’s Security and Login screen.
