@the0ther @IceCubeSoup I don't know what Google Workspace does tbh nor have I used an SSO system per-se but it would be pretty easy to set up any number of servers with just one login cred.

Just a few off the top of my head:
-root-only linux
-single-user linux

Also you can use mumble (I think) for teleconferencing.
