MFA outage when receiving codes via text and phone messages – Resolved

Description

Update December 6, 2024, 5:00 pm:

The issue with text messages and phone calls for MFA has been resolved. We will continue to monitor this situation over the weekend.

We still recommend all users have Microsoft Authenticator activated as an MFA option moving forward. (See instruction below for activation)

You should be able to authenticate with MFA to all applications including Email, Teams, Zoom, Microsoft products, MyGateway, and canvas.umsystem.edu

Update December 6, 2024, 12:45 pm:

This issue has been verified with Microsoft. Unfortunately, they have been unable to give us a time for resolution.

This may be causing difficulties for employees and students who are attempting to access a variety of services that require multifactor authentication, such as email, PeopleSoft, Canvas, Teams, Zoom and more.

MFA is still working properly with the Microsoft Authenticator App. Please choose this option if you have it available to you.

We recommend everyone have the App, even if you are not currently experiencing an issue.

To install the Authenticator App during this outage:

1. Install the “Microsoft Authenticator” app from your App store on your mobile device.
   1. Link for iOS
   2. Link for Android
2. Go to https://mysignins.microsoft.com/
