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 computer or mobile device Facebook doesn't recognize. You can also get alerts when someone tries logging in from a computer Facebook doesn't recognize.

To turn on or manage two-factor authentication:

Go to your Security and Login Settings by clicking in the top-right corner of Facebook...
