Answer 2

If access to the Microsoft Authenticator app and the original QR codes is lost, recovery depends on whether there is still access to any security info or backup.

1. If this is a personal Microsoft account and the password is known:
   • If there is access to some security info (another phone number or email):
     1. Go to the Advanced security options page for the Microsoft account and sign in.
     2. Select Add a new way to sign in or verify and set up a new phone/email for codes.
     3. Verify the new method with the code sent.
     4. Expand the old verification method that is no longer accessible (Authenticator/old phone) and select Remove.
   • If there is no access to any security info:
     1. Start sign-in to the Microsoft account.
     2. At the Verify your identity prompt, choose I don't have any of these.
     3. Follow the steps to replace security info. After replacement, sign-in will be blocked for 30 days while the change completes. Existing security info can still be used during this period, and using it cancels the change.
   • If the password is also forgotten and no security info is accessible:
     1. Review the guidance in Help with the Microsoft account recovery form.
     2. Submit the account recovery form using Recover account.
2. If this is a work or school account and the password is known:
   • If there is access to some security info:
     1. Sign in to the Advanced security options page for the work or school account.
     2. Select Add a new way to sign in or verify, configure a new method, verify it, then remove the old method that is no longer accessible.
   • If there is no access to any security info:
     1. Begin sign-in to the work or school account.
     2. At Verify your identity, select I don't have any of these.
     3. Follow the instructions to replace security info. After replacement, there is a 30‑day wait before sign-in with the new info.
   • If the password is forgotten and no security info is available, follow the Help with the Microsoft account recovery form and submit a recovery request.
3. If the Authenticator backup itself cannot be restored:
   • If the backup account for Authenticator cannot be accessed, support cannot restore Authenticator credentials. Use the Microsoft account sign-in helper to regain access to the backup account, or re-add accounts manually following the normal “add your accounts to Microsoft Authenticator” process once sign-in is working again.
4. If this is a work or school account and no alternative method works and there is no admin access:
   • Contact the organization’s Help desk or IT admin and ask them to clear or reset MFA/security info for the account so that registration with Authenticator can be done again.
