DUO Multi-Factor Authentication is currently experiencing an issue with their service, where T-Mobile & Sprint customers are failing to receive DUO messages to authenticate and log in.

If you are experiencing this issue, you can use alternate methods of authentication, such as a phone call and/ or PUSH.

We do not know of an expected time of resolution, but we will update this post as soon as we have additional information. If you are experiencing issues, please contact the ITS Service Desk at 740-587-6395 or email servicedesk@denison.edu.
