Set Up Microsoft Authenticator App for MFA

Summary

Microsoft is retiring SMS (text message) and voice call authentication for Microsoft 365 on February 1, 2027.

To prepare for this change, Winona State University is transitioning Microsoft 365 users who currently rely on text messages or phone calls for MFA to approved authentication methods.

Winona State University recommends the Microsoft Authenticator app, but other approved authentication methods are also available.
