Adding an Admin

You can designate players as admins using their SteamID64 in the CONFIG_server.cfg file.
You will need the SteamID64, which you can obtain, among other ways, from here: https://steamid.io
Your server must also be in Advanced mode.

Enter the players as follows:

    admins[]=
    {
        "SteamdID64",
        "SteamdID64",
        "SteamdID64",
    };

You can then simply log in as an admin on the server using the #login command without specifying a password.
