Two-factor authentication is a security feature that helps protect your Facebook account in addition to your password. If you set up two-factor authentication, you'll be asked to enter a special login code or confirm your login attempt each time someone tries accessing Facebook from a browser or mobile device we don't recognize. You can also get alerts when someone tries logging in from a browser or mobile device we don't recognize.

To turn on or manage two-factor authentication:

1. Go to your Security and Login Settings.
2. Scroll down to Use two-factor authentication and click Edit.
3. Choose the security method you want to add and follow the on-screen instructions.<
4. When you set up two-factor authentication on Facebook, you’ll be asked to choose one of three security methods:

• Tapping your security key on a compatible device.
• Login codes from a third party authentication app.
• Text message (SMS) codesfrom your mobile phone.
