[HELP] Making steam required to join a server

Hello so I found this:

In citmp-server.yml, there is this line:

# set to false to require players to be signed in to Steam
DisableAuth: true

But I am not sure where to find the citmp-server.yml, help please.

This has been changed to server.cfg years ago.

Where in the server.cfg can I find it?

You can’t “find it” anywhere, you have to create it yourself an example can be found on the docs HOWEVER why would you want to deny users to join without Steam? that seems like a bad thing to do as some people don’t always want to use Steam.

I tried the key, it did not work. Is there a specific domain I am supposed to be using?
