How to Turn on Two-Factor Authentication on Facebook

This article explains how to turn two-factor authentication on and off on the Facebook website.

How to Activate Two-Factor Authentication on Facebook

Facebook accounts often contain a great deal of personal information and other private data, so it's important to know how to activate two-factor authentication (2FA) on Facebook. With 2FA enabled, you are asked to validate your identity each time you log in. Validation uses methods that include entering a one-time code sent to your mobile device or approving the authentication attempt on another trusted device.

1. Go to your Facebook home page and click the down arrow in the upper right corner.

2. Click Settings & Privacy > Settings in the menu.

3. Select Security and Login in the left pane.

4. Scroll down to the Two-Factor Authentication section and select Edit located next to Use two-factor authentication option.

5. Enter your Facebook password and click Continue to open the Two-Factor Authentication dashboard for your account.

6. For 2FA, choose between receiving text messages with a code or using a third-party app.

   For text messages, you can use a phone number already associated with your Facebook account or choose a new one to receive these texts.

7. Select an optional backup method. You have the option of using a static recovery code only you know or tapping the security key (such as Touch ID) on a compatible device.

   These backup methods are not mandatory but are recommended in case you cannot access your primary 2FA device or application. To configure either, select Setup next to the Security Key or Recovery Codes option. 

When 2FA is first enabled, you are asked if you want to save the computer, smartphone, or tablet you're currently logging in from. If you opt to do this, you won't be required to enter a security code every time you access Facebook from the device in question. You shouldn't do this on public computers or other devices used by other people.
