Factorio Admin Commands
Admins are listed in the server's server-adminlist.json (in the SurvivalServers Command Center this is the Server Config › Access Control › Admins field). Admin commands work from in-game chat and over RCON.
In-game /promote, /ban and /whitelist changes are replaced at the next start: the panel rewrites all three lists from those Access Control fields.
Player management
/promote <player>: give a player admin/demote <player>: remove admin/kick <player> <reason>: kick a player/ban <player> <reason>: ban a player/unban <player>: lift a ban/bans: list banned players/mute <player>//unmute <player>: mute or unmute chat/purge <player>: clear a player's chat history
Whitelist
/whitelist add <player>//whitelist remove <player>/whitelist get: show the whitelist/whitelist clear: empty the whitelist (an empty whitelist lets anyone join)
Server
/players online: list connected players/admins: list admins/server-save: save the map immediately/kick,/banand the commands above all work over RCON too/config get <option>//config set <option> <value>: read or change runtime settings such asmax-playersandpassword
A warning about Lua commands
/command (or /c) executes raw Lua and unlocks cheats like item spawning, but using it permanently disables achievements on that save, and the game warns you once before it does. That is the game's own rule, not a hosting limitation.
