There are two ways to give a user admin permissions on your Factorio server.
The simplest way is to use the server console and use the `/promote {username}` command. If the command was successful the console will show a message reading: "{username} was promoted to admin by <server>".
Alternatively you can manually edit the `server-adminlist.json` file in the main directory of your server.
What new commands can Admins use?
- `/admin`
Activates the player management GUI. - `/ban {player} {reason}`
Bans a player from the server. - `/unban {player}`
Unbans a player from the server. - `/demote` {player}
Demotes a player from admin. - `/kick {player} {reason}`
- Kicks a player from the server. This player can re-join the server.
