How to enable (or disable) two-factor authentication on Facebook

There’s a reason people say you shouldn’t share your passwords for websites. In most cases, if somebody knows your password, there’s nothing stopping them logging in at will and running amok with your account. Two-factor authentication (2FA) makes it one step harder for anyone to access your account, should your password fall into the wrong hands through a data breach.

In short, when you log in on a new device, you’ll be sent a text message to confirm it’s you. The thinking is that even if a hacker has your password, they’re unlikely to have your phone.

It’s not foolproof, but it’s a damned sight better than nothing and will be enough to deter hackers in most instances. In theory, the phone number you supply to Facebook should *only* be used for authorising your identity. Recently there have been reports of Facebook using that number to send SMS spam to users. Below we’ve explained how to enable two-factor authentication on Facebook, and how to turn it off again if you no longer want to use it.

How to enable 2FA on Facebook

  1. Logging in to Facebook would be a good start. Once in, go to Settings by clicking the little downwards arrow in the top right-hand corner. Settings are second from the bottom.
  2. Click “Security and login”. It’s in the navigation bar on the left-hand side, right underneath general.
  3. Under Security and Login, scroll down to Two-Factor Authentication then click Edit.
  4. All that’s left now is to pick the kind of 2FA you want to use with Facebook. Most people will choose to receive an SMS text message with a code, but you can also generate a verification code using the Authentication App.
  5. To disable two-factor authentication on Facebook, repeat the above steps, and switch the setting from On to Off.
