Microsoft Multi-Factor Authentication (MS MFA) with MS Authenticator App - Quick Start Guide


  • This guide illustrates the one-time activation process upon first log in to a service requiring Microsoft Multi-Factor Authentication.

  • MFA means when you log into certain campus applications, you provide two authentications of your identity.

  • The first authentication method is your Beach ID login.

  • The recommended second method is the MS Authenticator mobile app

    • SMS text message and phone call options are also available. For employees or students without a compatible device, a hardware token can be requested.

  • After setup, each time you access Campus Single Sign-On (SSO) you will be prompted for MFA. 

  • MFA will also be required for Microsoft products you have installed on your computer such as Outlook or Office; however, your MFA approval will be remembered, and you won't be prompted again unless you've been inactive in that application for 90 days or you change your password.
