How to Recover a Facebook Account Removed from Microsoft Authenticator
Question details
The user needs to regain access to their Facebook account after the authentication configuration was accidentally deleted from the Microsoft Authenticator app without a backup.
- Product
- Microsoft Authenticator / Facebook
- Device & OS
- not provided
- Scenario
- Attempting to log into Facebook but unable to pass the two-factor authentication (2FA) prompt because the authenticator app no longer generates the required security codes.
- Observed behavior
- The Facebook account configuration is completely missing from Microsoft Authenticator, and the app cannot independently recover or recreate the deleted connection.
Before beginning the recovery process, check if you are still logged into Facebook on another browser, computer, or mobile device, which may allow you to bypass the 2FA prompt and update your settings directly.
Use Saved Facebook Backup Codes
The fastest way to regain access is by using the emergency backup codes provided by Facebook when you initially configured two-factor authentication.
When you set up 2FA, Facebook prompts you to save a list of 8-digit recovery codes. These codes are specifically designed to help you log in if you lose access to your authenticator app.
Navigate to the Facebook login page and enter your standard username and password.
When prompted for the 6-digit authentication code, click on the 'Need another way to authenticate?' or 'Having trouble?' link on the screen.
Choose the option that allows you to use a backup code or recovery code.
Type in one of your saved 8-digit backup codes to access your account. Once logged in, immediately go to your Security Settings to reconfigure a new authenticator connection.
Submit Identity Verification to Facebook
If you do not have backup codes, you must use Facebook's official account recovery process to verify your identity. Microsoft cannot restore the authenticator connection.

Frequently Asked Questions
Can Microsoft Support restore my deleted Facebook Authenticator configuration?
No. Microsoft Authenticator simply generates codes locally based on a shared secret key. Once the account is deleted from the app without a cloud backup, Microsoft cannot recover the account or recreate the authentication configuration. You must use Facebook's recovery tools.
Does Microsoft Authenticator have a cloud backup feature?
Yes, Microsoft Authenticator supports cloud backup for iOS (via iCloud) and Android (via a personal Microsoft account). However, this feature must have been turned on before the Facebook account was deleted in order to restore it on a new device or after an accidental deletion.
How do I set up 2FA for Facebook again after recovering my account?
Once you successfully log back into Facebook, navigate to Settings & Privacy > Settings > Security and Login. Under the Two-Factor Authentication section, click Edit, remove the old authenticator app connection, and set up a new one by scanning the new QR code with your Microsoft Authenticator app.
What if my ID is rejected by Facebook during the recovery process?
If your ID is rejected, ensure that the photo is well-lit, clearly legible, and that the name and date of birth match your Facebook profile exactly. You may need to retake the photo and resubmit your recovery request through the Facebook Help Center.
