Question details

The user is unable to log into their university Microsoft 365 account because the Multi-Factor Authentication (MFA) requires verification via an outdated phone number.

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to log into a university account using a new phone, but unable to register an authenticator app like FreeOTP or receive verification codes because the account is tied to an old phone number.
Observed behavior: The system prompts for a verification code sent to an old, inaccessible phone number, preventing account access.

Before you start

Ensure you have your student ID or other identity verification documents ready, as your university's IT support team will likely need to verify your identity before making security changes to your account.

Solution 1Recommended

Contact Your University IT Administrator

Because university accounts are centrally managed, only an IT admin can reset your MFA settings or update your registered phone number.

Microsoft 365 university accounts are enterprise-level accounts managed by the educational institution. Individual users cannot bypass Multi-Factor Authentication (MFA) without administrative intervention.

Locate IT Support

Go to your university's official website and search for the IT Helpdesk, Support Portal, or student tech support contact information.

Request an MFA Reset

Contact them via an alternative email, phone call, or in-person visit. Explain that you have a new phone number and request a reset of your Microsoft 365 Multi-Factor Authentication (MFA) settings.

Set Up New Authentication

Once the administrator clears your old settings, log into your Microsoft 365 account. You will be prompted to register your new phone number or set up a new authenticator app.

Re-registration Required: After the IT administrator resets your MFA, your next login attempt will require you to go through the initial security setup process again.

Solution 2

Request Help from Another Global Administrator

If you are part of a smaller faculty team or department with multiple admins, another Global Admin can reset your MFA.
