How to Recover Facebook Account When Microsoft Authenticator is Lost
Question details
The user is unable to log in to Facebook because they switched to a new phone and their Microsoft Authenticator app did not restore the Facebook two-factor authentication (2FA) credentials.

- Product
- Facebook and Microsoft Authenticator
- Device & OS
- not provided
- Scenario
- Switching to a new mobile device and attempting to log into a Facebook account secured by two-factor authentication without the original Authenticator data.
- Observed behavior
- Microsoft Authenticator fails to provide the required 2FA code, completely blocking access to the Facebook account.
Before proceeding with account recovery, check if you are still logged into Facebook on an older device, a trusted web browser, or the Messenger app, as you may be able to bypass the 2FA prompt or reset your security settings from there.
Recover Account via Facebook Support
Use this method since Facebook ultimately controls access to its accounts and the recovery of its associated two-factor authentication methods.
Because Microsoft Authenticator is simply a third-party app generating codes based on a saved secret key, Microsoft cannot recover your Facebook account for you. You must go directly through Facebook's official account recovery process to verify your identity and bypass the missing 2FA code.
Navigate to the official Facebook Help Center at https://www.facebook.com/help on a web browser.
On the Facebook login page, click 'Need way to authenticate?' or 'Having trouble?' when prompted for your login code. Select the option indicating you don't have your phone.
Follow the on-screen prompts to submit an alternative email address and upload a recognized form of photo ID. Facebook support will review this to confirm account ownership and remove the 2FA requirement.

Frequently Asked Questions
Why didn't Microsoft Authenticator transfer my Facebook 2FA to my new phone?
For security reasons, some third-party accounts do not automatically sync their secret keys when restoring Authenticator on a new device. You usually need to re-scan the original QR code provided by the service (like Facebook) or rely on backup recovery codes.
Can Microsoft support help me recover my Facebook account?
No. Microsoft has no access to Facebook's systems or your specific social media data. You must use Facebook's account recovery tools and ID verification processes to regain access.
How can I avoid losing 2FA access when changing phones in the future?
Before wiping or getting rid of your old phone, generate and save backup recovery codes from Facebook's security settings. Alternatively, temporarily disable 2FA on your accounts and re-enable it once your new phone is fully set up.
