Update to authentication options for Microsoft 365 services on 5-29-2026

Scheduled for May 29, 19:00 - 20:00 EDT

Scheduled

Information Resources & Technology is making changes to our Duo two-factor authentication integration with Microsoft 365 services to address an ongoing authentication issue for some users.

What This Means

- Some users were able to select options other than the ones we support — Duo Mobile or a hardware token — to authenticate their identities when logging in to Microsoft 365 services. The additional options, including MS Authenticator, have caused authentication issues for some users.
- At 7 p.m. on Friday, May 29, we will remove additional authentication options for Microsoft 365 services. After we make that change, you must use Duo Mobile or a hardware token to authenticate to Microsoft 365 services.
- If you previously used a non-supported authentication option, you will need to set up a supported option.

What You Might See After May 29

The next time you sign in to a Microsoft service (such as Outlook, Teams or OneDrive), you may see a screen titled "Let's keep your account secure." Select Next and follow the prompts to set up a supported authentication method.

Once complete, all future logins to Microsoft 365 services will prompt you to authenticate with Duo Mobile or a hardware token.

Troubleshooting Help

If you are repeatedly logged out and prompted to log back in to an affected service multiple times in a short window of time, please try the following steps:

1. Log out of the affected service.
2. Restart your device.
3. Log back in to affected service.

Note: If you are logging in to the browser version of a service or application, please use an incognito window.
