We all know someone who has had their Facebook account hacked — probably an uncle or a grandparent. To prevent any sort of hacking taking place on your account, it is important to set up two-factor authentication.

Two-factor authentication provides social media users an extra layer of security for their accounts by connecting them to different devices or applications. Facebook allows its users to set up two-factor authentication using their phone numbers or with a third-party authentication app. Here’s how to do both.
