- Under Settings, then Game Settings, fill in Owner Steam Name with your Astroneer profile name, spelled exactly as it appears in game.
- Fill in Owner Steam ID 64 with your own 17-digit SteamID64 (it starts with 7656119). Both values are required, so fill in both before you start the server.
- Restart the server so the values are written, then join with that same Steam account.
- Press Esc in game and open the server admin menu (the icon with a crown) to manage the session and use the whitelist.
- A password set in the in-game admin menu is replaced by the Server Password setting each time the server restarts. To change the password for good, change it under Settings, then Game Settings.
- To hand ownership to someone else, change both fields to that person's name and SteamID64 and restart. Only one owner can be set this way.
Good to know
- Only give admin rights to people you trust.
