How to enable 2FA for your Facebook account
Updated June 5, 2026
A step-by-step guide on how to set up two-factor authentication (2FA) for your Facebook account using Authenticator App. With 2FA enabled, signing in requires both your password and a temporary verification code — keeping your account safe even if your password is stolen.
Download Authenticator App
First, download the Authenticator ℠ App on your Apple device. Click the button below or scan the QR code with your iPhone camera.
Get the Authenticator ℠ App
Scan the QR codes from Facebook and generate secure one-time codes.
Log in to Facebook
Open the Facebook app while signed in and go to your profile, then tap the three lines (menu) in the bottom-right corner.
Open Accounts Center
Scroll down and tap Settings & privacy, then Settings, then open Accounts Center (See more in Accounts Center).
Go to Two-factor authentication
In Accounts Center, tap Password and security, then tap Two-factor authentication.
Pick your account and choose Authentication app
Select the Facebook profile you want to protect and verify it if prompted, then choose the Authentication app method and tap Next.
Copy the key or view the QR code
Facebook will show a setup key and a QR code (barcode). Copy the key, or take a screenshot of the QR code, so you can add it to your Authenticator App on the same phone.
Add Facebook to your Authenticator App
Open the Authenticator App on your iPhone and tap the + button. Either choose manual entry and paste the secret key (filling in the service and account name), or choose Photo/File to scan the screenshot of the QR code and add the account automatically.
Get your 6-digit Facebook code
Once the account is added, the Authenticator App shows a 6-digit code for Facebook that refreshes regularly. Tap the code to copy it.
Confirm the code in Facebook
Go back to the Facebook app and tap Next, then paste or type the 6-digit code when prompted and tap Next again to finish turning on two-factor authentication.
Save your recovery codes
After two-factor authentication is on, save the recovery codes Facebook provides somewhere safe. Each works once and lets you log in if you ever lose access to your authenticator app.
Backup & recovery
Facebook provides a set of one-time recovery (backup) codes you can use to log in when you don't have access to your authenticator app. Save them somewhere secure; each code works once. You can view, save, or regenerate a new set of recovery codes later from the two-factor authentication settings in Accounts Center (Password and security). The exact recovery-code labels were not confirmable from the (truncated) official pages, so this is described generically.
That's it — your Facebook account is now protected with two-factor authentication. If you have any issues during setup, visit the official Facebook help page. Stay safe!
