Question

Authenticator is not working anymore. I tried resetting my device and deleted the account off my Authenticator and cannot complete sign-in. I do not have QR CODE anymore

Answer 1

If your Microsoft Authenticator is not working and you no longer have access to the QR code or the account, you will need to reset your multi-factor authentication (MFA) settings. Here are the steps you can take:

1. Contact Your Administrator: If you are part of an organization, reach out to your IT administrator. They can reset your MFA settings through the Microsoft Entra Admin Center. They will need to navigate to Users > All Users, select your account, and then go to Authentication Methods to require re-registration of MFA.
2. Use Alternative Sign-In Methods: If you have alternative sign-in methods set up (like a phone number or email), try using those to access your account.
3. Contact Microsoft Support: If you are the only administrator or cannot reach an admin, you will need to contact Microsoft support directly. Explain your situation and ask them to escalate your request to the Data Protection team, who can assist you in resetting your MFA settings.
4. Follow Support Prompts: When you call Microsoft support, follow the prompts carefully to ensure your issue is directed to the right team. You may need to provide verification details to confirm your identity.

By following these steps, you should be able to regain access to your account and set up the Authenticator app again.
