Reset Microsoft Authentication app registration

If you have removed your Microsoft account from the Microsoft Authenticator app and are unable to log in to your Volume License Account, you can try the following steps:

1. Re-add your account to the Microsoft Authenticator app: Go to your account profile at your account profile and sign in with your organizational account. Then, select Additional Security Verification to reconfigure the Microsoft Authenticator app.
2. Use an alternate verification method: If you have previously set up alternative verification methods (like a phone number or email), try using those to log in. If you don't see an option for alternate methods, ensure that your account is set up correctly for MFA.
3. Contact your administrator: If you are part of an organization, reach out to your IT administrator for assistance. They may need to reset your MFA settings or provide you with a temporary bypass.
4. Troubleshoot MFA issues: If you continue to experience issues, consider checking if your account is configured for multiple verification methods. You can also try signing in again and select a different verification method on the sign-in page.

If these steps do not resolve your issue, you may need to open a support case for further assistance.
