Microsoft Authenticator Issue

Hi @Fred,

Thank you for posting your question in the Microsoft Q&A forum.      

Regarding your issue, may I kindly ask if you can contact your school IT Admin? If yes, can you reconfirm for me that your school IT Admin had done these exact steps to reset your Authenticator. 

Here are the steps: 

1. Sign in to the entra.microsoft.com as at least one Authentication Administrator. 
2. Select User -> All user.  Select the user (your account) to act on and select Authentication methods. then select Require re-register of multi-factor authentication.  
   • Require re-register MFA:  This disables all previous authentication methods. You'll then be prompted to configure a new MFA authentication method the next time you try to sign in, so you can set up from the start and add a new authenticator app.  

For more details, please refer to: Manage user authentication methods for Microsoft Entra multifactor authentication.

Note: Once re-registration is triggered, all your existing MFA methods such as phone numbers, Authenticator app, or other verification options will be removed. You will need to set up new MFA methods during your next login. Please ensure you have access to a valid phone number or the Microsoft Authenticator app before attempting to sign in again 

If they have done all those steps and couldn't be able to help you reset your Authenticator for you to log into your account, do comment for me to know.
