UPDATE 2/13/2025 5:55PM

Duo has been working to restore services and testing shows that Duo SMS and call requests for Denison logins are now completing normally. If you continue to experience problems, please report the issue via email to servicedesk@denison.edu.

UPDATE 2/13/2025 3:45PM:

Duo is still working to implement a fix. In the meantime, if you have an iPhone or Android phone but do NOT have the Duo Mobile app installed on it, you may now contact the ITS Service Desk. Access to the Duo Admin Console is now available so we can assist with Duo Mobile activations. However, those must be provided via email. To receive an email activation, you will either need to have access to your Denison email address or to visit the ITS Service Desk in Fellows 100A or call 740-587-6395 to complete identity verification steps and provide an alternate email address.

Duo is experiencing an issue that is causing SMS and call delivery failures. Due to this issue, the only available methods to approve logins are Duo Mobile pushes and passcodes, hardware tokens, and security keys. If you have one of these methods available, please use it to approve your login. 

Unfortunately, due to this issue the ITS Service Desk cannot assist with enabling these methods if you don’t already have them set up.

Duo is working to implement a fix. You can find more information directly from Duo on their status page.

We will update this post as soon as the issue is resolved.
