I didn't receive the MFA notification, what do I do?

On the login screen, there is a link to "sign in another way"

Depending on how you have set up MFA you can choose one the following:

• Text
• Approve a request (only for Microsoft Authenticator App users)
• Verification code from mobile app (only for Microsoft Authenticator App users)

What app should I use for authentication on my mobile device?

If you want to receive a push notification on your smart phone or tablet, be sure to download the Microsoft Authenticator app. 

Be sure to allow the app to send you notifications and access your camera to complete the setup process.

I will be traveling or studying abroad, which verification method should I use?

We recommend using the Microsoft Authenticator App if you travel or need to access your St. Thomas account while out of the country.  

The app does a push notification (a pop up on your phone you approve to verify that it is you logging in).  It also generates a 6 digit code every 30 seconds if the push notification isn’t available.  The code doesn't require you to be on the Internet or connected to data, so you don't need phone service to sign in which is a plus for travelers.
