Offline Access with YubiKey over RDP

[embj]

Is it possible to setup offline access with a YubiKey over an RDP session?

I purchased a YubiKey over the weekend primarily for this purpose, but I haven’t been able to get Duo to detect the key when trying to set up offline access.

I know the key is being passed through correctly to the RDP session because I have configured it for smart card authentication and can see that it is being detected on the Windows logon screen, just not by Duo.

Thanks.

Hi @embj,

No this is not possible today. We use the U2F functionality of the Yubikey, and U2F is currently not supported via RDP. It is supported for offline local logon only.
