The first admin
The first player to join a new server is made admin by the game. Admins can make other players admin from the player list in game.
What admins can do
- Kick a player.
- Ban a player: they cannot come back until the ban is lifted.
- Make another player admin, or take it away.
The files
Admins.json in the save path lists admins by SteamID64 (17 digits starting 7656119). PlayerBans.json lists the bans. The server writes both back when it stops, so edit them only while it is stopped.
On Flux, the Admins & Bans tab does it for you: add an admin by SteamID64, by Steam profile link or from the players who have played, remove one, or lift a ban, and the server restarts with the change.

How do I make myself admin on a Core Keeper server?
Join it first: the first player becomes admin. Otherwise add your SteamID64 to Admins.json while the server is stopped, or on Flux in the Admins & Bans tab.
How do I unban someone on a Core Keeper server?
Remove them from PlayerBans.json while the server is stopped, or on Flux, press Lift Ban in the Admins & Bans tab.
