How to setup Microsoft Authenticator

Android users accessing their work email must use the Microsoft Outlook for Android app. The native email app doesn’t support the correct method of authentication needed for Microsoft MFA.

Apple users can use either the Outlook for IOS app or the default Mail app, but Sentrian recommends Outlook for IOS for the best experience with Office 365.

Setting up the app

MFA is a very important part of online security. Verifying your identity using a second factor such as your Smart Phone prevents anyone but you from logging in, even if they know your password.

Setting up MFA on your phone is quick and easy, and once setup will only require you to select ‘Approve’ on a notification rather than entering a code like you might be used to with other MFA.

  1. Browse to the following address on your computer and login

    https://aka.ms/mfasetup

  2. Click next on this screen

  3. Download the Microsoft Authenticator, then choose Next

    The MFA app can be downloaded via the following links:

    Microsoft Authenticator for Android

    Microsoft Authenticator for IOS

  4. Follow the steps described

    Follow the instructions on the screen:

  5. On your phone

  6. Scan the QR code on the screen with your phone, then click next

  7. Microsoft will now send a notification to your phone

  8. On Your phone, select the notification, then choose Approve

  9. Setup complete

For future sign in’s, you will be prompted like below and will receive a notification on your mobile.
