Setting up Multi-Factor Authentication (MFA)

Before You Start

  • Read this whole guide first!
  • This process works best using two different devices. 
    • A phone or mobile device to receive MFA prompts (steps below marked "On your phone:")
    • Another computer or device to access your account (steps below marked "On your web browser:")
  • Review supported mail apps: This is an important step since most built-in mail apps don't support MFA.
    • See the App Compatibility chart below.
    • Android: Only Outlook App works.
    • iOS: Only specific versions of Mail app works, otherwise you need the Outlook App.
    • If you do not have a supported app, you will need to install one. 
  • Review recommendations: 
    • Install Microsoft Outlook on your mobile phone/devices
    • Install the Microsoft Authenticator app on your mobile phone/devices
    • Decide what "factors" you will use during setup. 
  • Other Information
