Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Contact your college’s IT help desk and ask them to require MFA re-registration for your account, because all currently available verification choices depend on the inaccessible Authenticator registration.
What to send the college help desk
Use wording such as:
I am locked out of my college Microsoft account. The only sign-in methods offered are an Authenticator approval or Authenticator verification code, and “I can’t use my Authenticator app right now” returns to the same screen. Please verify my identity and select Require re-register MFA for my account.
Only the institution’s administrators can reset an organization-managed account when no usable alternative verification method is available. This is also the accepted resolution for the same college-account sign-in loop reported by other users.^1^
Instructions for the college administrator
An administrator with at least the Authentication Administrator role should:
- Sign in to the Microsoft Entra admin center.
- Go to Entra ID → Users.
- Select your user account.
- Select Authentication methods.
- Select Require re-register MFA and confirm the action.
This removes the registered Authenticator and other listed MFA methods so that a new method can be configured at the next sign-in.^2^
After IT completes the reset:
- Start a new sign-in to the college account.
- Follow the registration prompt.
- Add the college account to Microsoft Authenticator and scan the displayed QR code.
- Complete the test approval or code prompt.
- If your college permits it, register an additional recovery method to avoid another Authenticator-only lockout.
Do not uninstall or reinstall Authenticator while locked out; doing so does not reset the MFA registration stored by the college. Also avoid repeated sign-in attempts, because unusual or excessive attempts can temporarily prevent further authentication attempts.^3^
