Duo CA Pinning Bundle Update – Action Required for Out-of-Date Clients Impacting All Deployments
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Feb 10, 2026 - 15:00 EST
Scheduled - Beginning February 2nd, customers using outdated Duo-connected applications or clients may experience authentication failures. Impacted customers should update all affected applications and Duo Mobile apps to the latest versions with the new Duo CA pinning bundle. Impact can be confirmed via the Unsupported Clients Log in the Duo Admin Panel, and full guidance is available in Duo documentation and Cisco Field Notice FN74372.
