    Hi there,

    I am using NoMachine 7.10.1 with Kubuntu 22.04.01 on several fresh OS setups and computers. On all of those systems, I can reproduce the following problem:

    After adding “auth required pam_google_authenticator.so” to the file /etc/pam.d/nx (which successfully finalizes the 2FA configuration) I can no longer enable changing secure server settings in the GUI. This is independent of any remote connection.

    Clicking on “Changes disabled” triggers a password prompt as usual. However, entering the correct password yields no error message (as opposed to entering a wrong password) and does not enable changing the secure settings. Instead, the GUI freezes and does not allow any menu input.

    After commenting out the “auth required…” line in /etc/pam.d/nx and restarting the Nomachine GUI (via Quit NoMachine Player), I can access the secured settings again (i.e. clicking “Changes disabled” turns to “Changes enabled” after password entry).

    Of course I can still change settings by editing the config files directly or by temporarily disabling 2FA. But I would like to know if anyone else has encountered this problem and found a better solution than that.

    Thank you and kind regards



    thanks for taking the time to report this. The GUI preference changes don’t currently support pam_google_authenticator but we will be adding it in one of the next releases. In the meantime you can continue to edit the CFG files as you have already been doing.


    Roger that, thank you for the swift response!
