To regain access to your account when you cannot use the Microsoft Authenticator app, you can follow these steps:
- Use Alternative Verification Methods: If you have set up multiple verification methods, try signing in again and select a different method on the sign-in page. This could include receiving a verification code via SMS or a phone call.
- Account Recovery: Since you are an administrator, you may have the ability to reset your account or initiate the registration process again. You can manage user and device settings through Microsoft Entra multifactor authentication.
- Contact Support: If the above options do not work, consider opening a support case to troubleshoot further. Microsoft support can assist you in recovering access to your account.
- Reinstall Authenticator: If you can access your old phone or if you have a backup, try reinstalling the Authenticator app and see if you can recover your account there.
- Reset App Passwords: If you have app passwords set up, you may need to delete them and recreate them once you regain access to your account.
These steps should help you resolve the authentication loop and regain access to your account.
