One of the strong security features that Facebook offers in order to guard your account against unauthorized access is Two-Factor Authentication (2FA). Once this feature is switched on, you will be required to have a special login code or confirmation on your device besides the password each time you log in to your account in a different location or in a different device.
Why Enable Two-Factor Authentication?
Two-Factor Authentication is one additional security measure that you would gain on your Facebook account. Here’s what it does:
- Hack-proof: No matter who steals your password, that person will not be able to log in without the second authentication factor.
- Gives real-time notifications: You will be alerted every time a strange log-in takes place.
- Allows several verification options: You may use SMS, authentication applications, or a security key.
