hi,
Players can be whitelisted as administrators on the server via their SteamID. These players can use cheat commands on the server automatically, as if they had authenticated themselves via the enablecheats command (described below).
To whitelist administrators, create the file ShooterGame/Saved/AllowedCheaterSteamIDs.txt. In the file, list each player's SteamID, one per line.
SteamIDs for all connected players can be listed in-game via the cheat ListPlayers command. Players can be kicked from the server (using their SteamIDs) via the cheat KickPlayer command.
