2026.3.17.0 Yubikey OTP is not working anymore

Hi,

I wanted to build a RDM package for installation via SCCM. I used the version 2026.3.17.0 and noticed that MFA with Yubikey OTP is not working anymore. When i roll back to the previous version 2026.3.12.0 we were using, then it works again.

Best Regards,

Joachim

Forgotten to mention: We are using DVLS 2026.3.7.0 as data source.

Hello Joachim,

Thank you for contacting Devolutions Support.

To narrow this down, could you describe what happens on 2026.3.17.0 when you sign in with your YubiKey? For example, does the OTP prompt come back after you use the key, or is an error displayed? If there is an error, please send the exact message or a screenshot.

Could you also confirm whether “Always ask for username” is enabled on the Devolutions Server workspace in RDM?

Best regards,

Samuel Dery

Hello Samuel,

thanks for your answer.

When I am trying to sign in, the MFA dialog pops up, I am pressing the Yubikey and it generates the 44 character code and I am pressing "Send". Then I see a message like trying to authenticate and maybe 2 seconds the MFA prompt appears again.

In the "Login attempts" table on the DVLS I always see the following sequence:

Username	Tags	IP	Source	Platform	Failure type	Creation date
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:16
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:16
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:16
meyerj@example.com		192.168.137.103	RDM	Windows	Success	11.09.2026 18:15
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:15
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:15
meyerj@example.com		192.168.137.103	RDM	Windows	Multifactor second step is required	11.09.2026 18:15

The option "Always ask for username" is not enabled.

Best Regards,

This seems to be not just Ubikey related. We encounter the exact same behaviour after updating to RDM 2026.3.16.0 or 2026.3.17.0 from 2026.3.12.0. Our MFA uses the built in DPS 2FA. Our current DPS version is 2026.3.7.0.

Rolling back to RDM 2026.3.12.0 helps.

Hi @proessel, @joachimmeyer,

Currently trying to diagnose, do you use WIndows Authentication in your RDM with DVLS?

Cheers,

Hello Luc,

yes we are using Windows Authentication in RDM.
