Hello Luc,

yes we are using Windows Authentication in RDM.

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.

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

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.

As far as I have seen, this dialog is only accessible if you are an administrative user and the settings under File -> Settings -> Security -> Lock are greyed out. But looks like you can also configure these settings via Group Policy which would be our preferred method:

Hello Min,

thank you very much!

Hi, we are currently evaluating Remote Desktop Manager with Devolutions Server as the data source (for tier 1 servers). We are currently discussing to install RDM on the tier 2 office client and the admin is logged on with the normal tier 2 office account without admin rights and launches RDM. The user would then use the PAM module to check out his tier 1 admin user to log on via the Devolutions Gateway to a tier 1 server without entering his tier 1 admin password. MFA via Yubikey OTP is enforced in Devolutions Server.

When the user starts RDM, he needs to authenticate via Yubikey OTP. This works so far. However, when he closes RDM and re-opens, MFA is not being enforced anymore. Only when I log off from the data source and log on again. Is there a way to force MFA more often, at least every time RDM is started?

Thank you!

Joachim
