Duo Certificate Pinning
Hi All, We have an alert that Duo Certs will be expiring and clients need updating:
Action Required by February 2, 2026: Announcing Duo certificate authority bundle expiration
- Please ensure that you update all affected applications as well as the Duo Mobile application on phones.
Failure to update the affected applications and application versions described in this guide will impact user access and authentication!
This guide provides background information about Duo's root certificate authority (CA) bundle replacement and guidance for updating affected applications before February 2, 2026.
I have check the DUO logs and the only application that is considered unsupported is Devolutions RDM:
Is there an update needed or am I missing something here? We are running RDM 2025.3.28.0 but I cannot see anything related to DuoAPICSharp on my machine so not sure if this is something embedded into RDM or am I over thinking this. If anyone has seen this and can point me in the right direction please shout.
Thank you
Lyndsey

Hello,
This is indeed on RDM's side. We went ahead and updated the DUO api client version to 1.1. Starting from version 2025.3.29.0, the log saying RDM is unsupported should disappear.

Hi All, We are still seeing the error for the mac OS version of RDM. RDM says its upto date with version 2025.3.9.2. Am I missing something again? Thank you Lyndsey
Hello,
The fix will be available in the next RDM Mac version, which should be available by early next week.
We will post it here once it's available for download.
Thank you for your collaboration.
