How do you give friends admin rights without a password to the server?

I was playing gmod with a friend and he couldn't use some admin items and I wanted to give him admin, but the tutorials we found said something about a password. We don't use a password when play; we just connect via ipv4 and the connect command. How do I give him admin rights?

After some research I found that you should be able to add admins by altering the users.txt file.
You can find this file in:
STEAMFOLDER > GarrysMod > garrysmod > settings > users.txt
In this file an entry looks like this:

"admin" { //"garry" "STEAM_0:1:7099" } 

What you should do is enter a line with the info of your friend so it ends up like this:

"admin" { "Friends_Username" "STEAM_0:0:0000" } 

You can find a steam id trough various websites or steam itself.
