UCAR and NSF NCAR’s Duo login experience will change on February 28, 2025

February 13, 2025

In order to comply with upcoming Multi-Factor Authentication (MFA) requirements from Microsoft, UCAR and NSF NCAR are enhancing their MFA system to provide improved security. This may affect applications that you access through Secure Sign On (SSO) with your CIT user ID and password—including Advanced Research Computing (ARC) login, the help ticket portal, and Derecho and command-line logins.

Starting on February 28, 2025, you will notice a small change during login. After entering your password, you’ll see an additional pop-up asking you to select Cisco Duo for authentication.

No action is required from you prior to this change. Starting February 28, when prompted, simply select Cisco Duo, and proceed with authentication.

If you have questions or need assistance, please submit a ticket to the NCAR/UCAR Service Desk (NUSD).
