Problem with Microsoft Authenticator

Question

Hello, Hello, my phone was stolen and I am trying to log in with my university email address, but I need a code from the Microsoft Authenticator app that I cannot receive because the code I should receive is connected to the app on my old phone... How can I disconnect my old phone and add my current phone to this app? That way, I could receive the code I need. I haven't found a way to do this, which is why I'm asking for help. Thank you in advance.

Answer 1

If your phone was stolen and you cannot access the Microsoft Authenticator app to receive codes, you will need to regain access to your account through alternative methods. Here are some steps you can take:

1. Use a Recovery Email or Phone Number: If you have set up a recovery email or phone number, you might be able to receive a verification code through those methods instead of the Authenticator app.
2. Contact Support: Since you are unable to access the Authenticator app, you may need to contact your university's IT support or Microsoft support for assistance. They can help you reset your multi-factor authentication (MFA) settings and allow you to set up the Authenticator app on your new phone.
3. Use a Break Glass Account: If you have a break glass account (an account that can bypass MFA), try using it to access your primary account and reset the MFA settings.
4. Follow Up with Microsoft Data Protection Team: If you are the only global admin for your accounts, you may need to escalate your issue to the Microsoft Data Protection team to help reset your MFA.
5. Re-register MFA: Once you regain access, you can re-register your MFA settings and set up the Microsoft Authenticator app on your current phone.

Make sure to keep your recovery options updated in the future to avoid similar issues.
