Gnome-remote-desktop without system credentials?

Hello,
For a multi-user headless RDP setup, is it possible to use gnome-remote-desktop without system credentials (the ones set up via sudo grdctl --system rdp set-credentials) ? If it is possible, is it a good idea?

The context of my question is

  • It feels like a weird user experience on the client side to have to provide two sets of credentials - the system ones and then the ones for the actual remote user
  • I don’t feel I understand what these system credentials guard against (in multi-user headless mode specifically) - an explanation, if somebody has it, will be much appreciated here, thanks!
  • In my real-world setup I envision the actual RDP access will happen over ssh port forwarding, which would entail three different credentials, making things especially unwieldy for me.

I’m new at all this, so apologies if some of it doesn’t make sense. Thanks!
