Managing 2FA on Facebook
Learn how to check which phone number receives your Facebook 2FA codes, switch to a more reliable method like Google Authenticator, and turn 2FA off when you genuinely need to.
What's covered
Why two-factor authentication matters
Two-factor authentication (2FA) is an important security feature on Facebook that helps protect your account from unauthorized access. When 2FA is enabled, Meta sends a verification code whenever:
You log in from a new device or browser
You attempt sensitive security changes
Meta detects unusual login activity
This article covers the three most common 2FA tasks: finding out which number your codes go to, switching to an authenticator app for more reliable delivery, and turning 2FA off if you ever need to.
Getting to your two-factor authentication settings
All three tasks below start from the same place, so here's the shared path first.
Step 1: Log in to Facebook
Open your browser (Google Chrome recommended) and visit https://facebook.com. Log in using the Facebook account that manages your Meta Business assets.
Step 2: Open Facebook settings Click your profile icon in the top-right corner, select Settings & Privacy, then click Settings.
Step 3: Open Meta Accounts Center On the left-hand navigation panel, locate Meta Accounts Center, and click the blue link See more in Accounts Center. This opens the Meta Accounts Center, where all security and login settings are managed.
Step 4: Go to password and security In Accounts Center, use the left-side menu and click on Password and Security, then Two-Factor Authentication. Choose the correct Facebook profile if multiple profiles are listed.
From here, jump to whichever task you need below.
How to check the phone number linked to your 2FA
Check the masked delivery number On the Two-Factor Authentication screen, Facebook shows where your login codes are being delivered.
View the full phone number Return to the Password and Security section in Accounts Center, locate and click on Personal Details, then select Contact Info. Meta will display the phone number saved in your account in full (unmasked), along with your email address — so you can clearly identify which number is connected to your two-factor authentication setup.
How to switch from SMS/WhatsApp to Google Authenticator
If your Facebook verification codes sometimes don't arrive by SMS or WhatsApp, switching to an authentication app like Google Authenticator is a more reliable option — it doesn't depend on network or SMS delivery and keeps working even without mobile signal.
Add the authentication app as a backup method From the Two-Factor Authentication screen, under Add a backup method, click on Authentication App. Facebook will ask you to verify your identity before proceeding.
Verify using your existing method A verification code will be sent to your registered phone number (SMS). Enter the code on your laptop screen and click Continue. You can now proceed with setting up the authentication app.
Setting up Google Authenticator on your phone
Install Google Authenticator On your mobile phone, go to Play Store (Android) or App Store (iPhone). Download and install Google Authenticator, then open the app.
Start setup in Google Authenticator Tap Get Started, then choose either Continue with Google account or Use without an account — either option works. Select Scan a QR Code and your camera will open.
Scan the QR code On your laptop screen, Facebook will display a QR code. Scan that QR code using your mobile camera, then click Next on your laptop.
Enter the 6-digit code Google Authenticator will now show a 6-digit code. Enter this code on your laptop screen and click Next. You'll see a confirmation message that Two-Factor Authentication is turned on using the authentication app. Click Done to complete the process.
How to disable 2FA on Facebook
Two-factor authentication adds an extra layer of security to your account — along with your password, you must enter a verification code sent to your email, SMS, or WhatsApp. If you need to disable 2FA for any reason, here's how.
View your current 2FA method On the Two-Factor Authentication screen, you'll see your current authentication method (SMS, WhatsApp, or authentication app), and a toggle button on the right side, currently turned ON.
Turn off 2FA Move the toggle button to the opposite direction (turn it OFF). A pop-up will appear asking for confirmation — click Turn Off.
Final verification A verification code will be sent via SMS to your registered phone number. Enter the verification code and click Continue. Once completed, two-factor authentication will be disabled.
Disabling 2FA reduces your account security. After turning it off, your account will only require a password for login, and anyone with your password can access your account. It's strongly recommended to re-enable 2FA as soon as you're done with whatever task required it off.
Key takeaways
2FA sends a code to your linked phone number (or authenticator app) whenever there's a new login, a sensitive change, or unusual activity.
Facebook masks your number on the Two-Factor Authentication screen — check Personal Details > Contact Info in Accounts Center to see the full, unmasked number.
Switching to Google Authenticator removes your dependency on SMS/WhatsApp delivery and keeps working even without signal.
You can keep SMS as a backup or remove it entirely once Google Authenticator is active.
Disabling 2FA means your account only needs a password to log in, so re-enable it once you're done with the task that required it off.
Frequently asked questions
Why is my phone number masked on the 2FA screen? Facebook only shows the last couple of digits on the Two-Factor Authentication page for security reasons. To see the full number, check Personal Details > Contact Info in Accounts Center.
Do I need to remove SMS/WhatsApp 2FA after adding Google Authenticator? No, it's optional. You can keep SMS as a backup method or remove it completely once Google Authenticator is working.
What happens if I lose my phone with Google Authenticator installed? You could get locked out of your account, so it's a good idea to keep a backup 2FA method like SMS until you're confident in your setup.
Is it safe to keep 2FA disabled long-term? No, it's not recommended. Disabling 2FA means your account can be accessed with just a password, which is a security risk.
What's a more secure alternative to disabling 2FA entirely? Instead of disabling it, consider switching to Google Authenticator for more reliable, network-independent verification.
