I have for the first time install and make a TS server work on my Linux server.

But I have one question that I Think maybe already have responded but I need help to find it because I'm not sure what to look after

That I want is easy (I Think) is that I like to create a channel that user can login with a password.
Nothing else, right now I just going to have one channel and only user that have a password is going to have access and only to connect so they can speak to each other, no config, no admin, nothing more then just so they can speak to each other.
