Top Hat is currently experiencing a site-wide issue with single sign-on. Currently, VCU users are unable to sign-in using their VCU accounts through our CAS single sign-on portal. This issue was first reported to us around 9:45am this morning (10/18/2024). This issue impacts most schools using single sign-on, not just VCU. We've already notified Top Hat support of the issue and their engineering team is actively working to restore service as quickly as possible. As we receive updates from Top Hat support we will provide them via our Classroom Technology blog at https://blogs.vcu.edu/classroomtechnology.

If you have questions or concerns about Top Hat, please reach out to the IT Support Center at (804) 828-2227 or by emailing tophat@vcu.edu.

Top Hat's engineering and support teams have identified the issue with Single Sign-On (SSO) authentication and have reached out to VCU Technology Services to update an expired certificate. Once this certificate issue has resolved and we are able to confirm a complete restoration of SSO authentication via VCU's CAS portal another update will be shared.
