The error you’re seeing usually means your account’s verification methods need to be updated or re-registered. Here are a few steps you can try:
1/ Check your verification methods:
Visit https://aka.ms/mfasetup and confirm that your Microsoft Authenticator app is listed and active.
2/ Update or re-register the Authenticator app:
- Open the Microsoft Authenticator app on your phone.
- If your school account isn’t listed, remove any old entries and add your account again by scanning the QR code from the MFA setup page.
For example:
3/ Clear app cache and ensure updates:
Make sure the Authenticator app is updated to the latest version and restart your device before retrying.
4/ Use another login option
When you try to log in at office.com, look for the "Sign-in options" link.
If your phone number was previously registered to your account, you may be able to choose to receive a verification code via SMS or phone call instead of entering your password.
5/ If you've tried the above steps but the issue still persists:
You can ask your IT admin to reset password and MFA via Admin Center (Browser Cache Method) of your account by following the steps below.
1 – Navigate to Microsoft 365 Admin Center, you can click Identity at the sidebar
Microsoft 365 Admin Center website: Microsoft 365 admin center
It will lead you to Microsoft Entra Admin Center (Microsoft Entra - Microsoft Entra admin center
Select Users

Click on to the affected account name (your account)
For example:
2 – Select "Authentication Methods"
3 – Click "Require re-register multifactor authentication"
Next time the user sign in, the system will require them to set up a new authentication method. By using this, the affected user can re-set up the right authentication method
