MFA Main Article: Set up O365 Multi-factor Authentication

General Information

What is Multi-Factor Authentication for O365?

  • Multi-Factor Authentication (MFA), also called 2-Factor Authentication (2FA), is a form of authentication which provides an added layer of protection, beyond just your password. This added authentication verification helps verify that a person logging in to an account is authorized to access that account.
  • Once you have enrolled in O365 MFA, after entry of your MinnState credentials to log in to O365 applications, you will receive a notification via the MFA notification option you selected during set up (a text, a phone call, or mobile Microsoft Authenticator App verification) to verify it is you logging in to your account.
  • The O365 multi-factor authentication is a service provided through the Minnesota State Microsoft O365 tenant. This solution helps protect not only your account, but all data and applications connected to the Minnesota State O365 tenant.   

Does Multi-Factor Authentication store my personal phone data?

  • No. None of your personal data is stored from any phone device you select for MFA set up and enrollment or by installing and using the Microsoft Authenticator app. MFA is not designed for data storage, it’s design and purpose is as an authentication utility. The Microsoft Authenticator app verifies authentication within the sign-in process in order to access Minnesota State O365 provided services.
