Two-factor authentication (also known as 2FA) is an extra layer of protection added to ensure that users attempting to log into an account are who they say they are. First, the password and username are entered. So instead of immediately gaining access to the account, you are prompted to provide another piece of information, such as a code.

You can get that code through text messages or by using a specialized authentication app you install on your mobile device. Once linked to your accounts, the app will generate a stream of random codes to use when needed. This method does not require an Internet connection to provide the code.



By activating this procedure you will get greater security that your social accounts are not compromised.

Set up two-factor authentication on Facebook

From computer

  • Go to Facebook and click the down arrow in the top right corner.
  • From there, select Settings and privacy> Quick links to privacy.
  • Scroll down until you reach the section Account security and click Use two-factor authentication.
  • Here you will be presented with two options. The recommended one is to use an authentication app to generate verification codes for added security. The second is text messages (SMS). This method uses text messages to send verification codes to your phone after logging into your Facebook account. If you want to select this option, click the button Use text message (SMS) and follow the steps.
  • To follow the recommended route, click the button Use authentication apps. A QR code will be generated on the display.
  • Open the authentication app, Google authenticator for example, and scan the QR code. An authentication code will now be generated by the app. It needs to be copied and pasted onto your Facebook desktop app.
  • That's all! Two-factor authentication is now active.

If you go back on the same path Settings and Privacy> Privacy Control> Account Security> Two-Factor Authentication, you will notice that you can now add a backup method so that you can log in even if your security method is not available. This includes text messages (SMS), security tokens, and recovery codes. It might be a good idea to set one of these in case you can't log into your account on a regular basis.

  • Tap the hamburger menu located at the top right and scroll down until you find Settings and privacy.
