Multi-Factor Authentication (MFA)

An introduction and setup guide

General Information  

Multi-Factor Authentication (MFA) is a security system that verifies your identity by requiring multiple credentials. Rather than just asking for a username and password, MFA requires additional credentials such as replying to a notification from an app on your mobile device or entering an authentication code.

Troubleshooting Tips - FAQ

  • Q: Under what circumstances would I want to reject an authentication prompt? 

If you get a prompt on your phone when you are not trying to login, you want to reject the request. This may be someone with your credentials attempting to login as you.

  • Q: I do not have a smartphone; can I still use MFA? 

Microsoft Authenticator Push notifications and authentication codes are preferred, but you may also elect to receive a phone call for verification.

  • Q: I pressed approve on the notification, but nothing happened. 

Microsoft Authenticator will send an approval notification, and after the user selects ‘approve’ it may not successfully send due to your phone screen being locked by biometrics (TouchID, FaceID etc.). Be sure your phone is unlocked when attempting to approve MFA notifications. 

  • Q: Is the Microsoft Authenticator app required? 

You may choose to use a phone call for authentication, this is helpful for those who do not have a smartphone, or for users requiring a user-friendly option.

NOTE: If you do include a phone number for phone-call verification set up an alternative phone number in case your device is lost or stolen so you may still authenticate.

  • Q: I decided to use phone call authentication, why aren’t the phone calls coming through?   

The phone call originates from (855)330-8653 check your phone settings, you might have ‘block all unknown calls’ configured on your phone, which will cause the call to not come in. You deactivate this setting to resume receiving the phone call, or add the phone number to your contacts list.

  • Q: I upgraded my phone to a different model, how do I transfer my authentication account to my new device?

When transferring to a new phone, you will need to remove the authenticator app from all applications on the phone, and repeat the initial setup instructions in this guide. If you do not remove everything, the Microsoft authenticator requests will still come through on your previous device. 

  • Q: I have a new phone number, how do I update my contact information for MFA?

To update your phone number go to the Security Verification page and update your phone number for your Authentication phone, office phone, or alternate authentication phone and click Save when finished.
