If you want to add extra security to your Facebook account, you can turn on two-factor authentication, so that you’ll need a login code any time you login to Facebook on a new phone or computer. Our guide will show you how to turn on two-factor authentication from within the Facebook mobile application.

Note: These screenshots were captured in the Facebook app on iOS.

Step 1: Tap the three lines in the bottom-right corner of the screen.

Step 2: Tap “Settings & Privacy.”

Step 3: Tap “Account Settings.”

Step 4: Tap “Security and Login.”

Step 5: Tap “Use two-factor authentication.”

Step 6: Tap “Get Started.”

Step 7: Tap either “Text Message” or “Authentication App,” depending on how you’d like to receive login codes when you’re logging into Facebook on a new device. If you choose “Text Message,” Facebook will send you login codes through text messages. If you choose “Authentication App,” you’ll need to use a separate app, such as Google Authenticator, to generate login codes.

Note: If you don’t have a phone number connected to your Facebook account, you’ll need to add one to use the Text Message option. Also note: You have the option to set up both text messages and an authentication app, but you’ll need to set them up one at a time.

If You Choose Text Message

Step 1: Once you tap “Text Message” in Step 7 above, you’ll receive a text message from Facebook containing a six-digit code. Enter this code in the Facebook app and tap “Next.” Note: The code in the screenshot below is only an example.

If You Choose Authentication App

Step 1: Once you tap “Authentication App” in Step 7 above, you’ll be taken to a screen containing a QR code and a text code. Either scan the QR code with your authentication app on another device, or switch from Facebook to your authentication app and enter the code Facebook provides.

Step 2: In the Facebook app, tap “Next.”

Step 3: Type the Facebook code generated by your authentication app and tap “Next.” Note: The code in the screenshot below is only an example.
