How to Login with Multi-Factor Authentication (MFA)

Once MFA is activated on your Office 365 account, your computer must be updated to at least Office 2016. If you are using an older version, such as Office 2013, you will not be able to sign in to Outlook or other applications with Office 365 MFA.
  1. Once MFA has been turned on for your Office 365 and/or Admin Banner, you will log in with your Office 365 email address.

    Please Note: Once MFA is activated on your Admin Banner account, you will no longer have a separate Banner username and password. You will log in with your Office 365 username and password: abc123@missouristate.edu
  2. You will see a screen similar to the one below when logging in with MFA on both Office 365 and Admin Banner, depending on the preferred verification option you selected in Step 2 above. The example below uses the Microsoft Authenticator app as the preferred option.

    Please Note: How often you are required to authenticate depends on several factors, including whether you are using a new device, a different browser, a browser in private/incognito mode, etc. You will be prompted to approve sign-in requests for every device that you log in with, including your work computer, laptop, mobile phone, tablet, etc. At a minimum, you will be prompted to authenticate your log ins to Admin Banner every seven (7) days and Office 365 every ninety (90) days. 
  3. If you are unable to authenticate with your preferred option you will be able to choose another authentication method from your selected options. Simply select Sign in another way to use a different method.

Once MFA is activated on your Office365 account, your computer must be updated to at least Office 2016. If you are using an older version, such as Office 2013, you will not be able to sign in to Outlook or other applications with Office365 MFA. You will also need to authenticate every instance where you are signed into an Office365 application. This includes:
  • Outlook on your desktop
  • The Outlook app on your mobile device(s)
  • Office365 online
  • Any Office365 mobile apps or desktop applications, such as OneNote, Teams, Groups, OneDrive for Business, and the Word, Excel, and PowerPoint apps.
  • The native email client on your mobile device, such as Mail on iOS. We highly recommend the Outlook mobile app for the best experience.
    • The native Android email client cannot be used with MFA. Please download the Outlook mobile app instead.
