Microsoft Multifactor Authentication (MFA)

Initial setup instructions:

For accounts created after March 31, 2021, your mobile number was registered as an MFA sign-in method during the account activation process.  If you are a returning student or have never registered for MFA, refer to this help Article.  


Update Your Sign-in Methods and Test Using MFA

Test MFA and verify your Sign-in methods at http://mysignins.microsoft.com/security-info.   Please ensure you have added a mobile phone number. Having the Authenticator app as your only sign-in method is not recommended.
 

Using MFA

Once you have registered sign-in method(s) for MFA, review the sign-in instructions.
 

New Phone Number or New Alternate Email Address

If you have the Authenticator app, see this article on how to update your phone number or alternate email address.  If you changed your phone number and do not have the Authenticator app, please contact the IT Service Desk (see contact info below).  Both United States and international phone numbers can be registered as an MFA sign-in method.
 

Install or Reinstall the Authenticator App (New Phone or Phone Reset)

Instructions to install or re-install the Authenticator app.  This allows you to receive Authenticator app notifications that you must "Approve."  Or, obtain a sign-in code by opening the Authenticator app and tapping your account.


Note that Multifactor Authentication cannot be removed from your account.
