Office 365 - Two-Factor Authentication (2FA)

Your password can be easily compromised. 2FA authentication increases your account security by requiring multiple forms of verification to prove your identity when signing into an application.

 Setting up a 2FA authentication will enable you to sign in using:
  • Push Notification Method - A notification will be sent to your smart device via the Microsoft Authenticator app. You will need to press "Approve" to continue with your sign-in.
  • Verification Code - A 6-digit code is generated in the Microsoft Authenticator app. You will need to type this code as part of your sign-in.
  • Phone Call - An automated system will call your cell phone or landline. You will be instructed to press the # key to confirm your sign-in.
  • Mail Applications on Older Devices may not be compatible with 2FA.
  • Review supported mail apps: This is an important step since some built-in mail apps do not support MFA.
    • See the 2FA Email App Compatibility chart below. 
  • Android: Outlook (Some built in Mail apps will also work. Try them out).
  • 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. 

Before doing the setup, see these recommendations and tips: 

·         Restart your web browser and close any Office 365 or Mail apps before starting this process.
