How do I set the Astroneer server owner?

Setting an owner (or admin) on your Astroneer dedicated server grants that player access to exclusive in-game management tools. To claim ownership, you need to configure your exact Steam username within the server’s configuration files, which then assigns your unique player ID the first time you join.

Caution

Always stop your server before editing configuration files. Any changes made to settings while the server is actively running will be overwritten and discarded the next time the server restarts.

Setting the server owner

1. Log into the AleForge Panel and Stop your Astroneer server.
2. Navigate to the Files tab and open the following folder pathway: Astro/Saved/Config/WindowsServer/.
3. Click to edit the AstroServerSettings.ini file.
4. Locate the OwnerName= line and set it to the intended admin’s exact Steam username (for example, OwnerName=SpaceExplorer99).
5. Locate the OwnerGuid= line and change its value exactly to 0 (so it reads OwnerGuid=0). This tells the server to prepare for a new ID.
6. Click Save Content, then start your server.
7. Have the designated owner connect to the server. Upon joining, the server will automatically authenticate their account and replace the 0 with their unique hidden ID in the OwnerGuid field.

How to transfer ownership

If you need to give admin privileges to a different player, simply repeat the process above. Stop the server, update OwnerName with the new player’s Steam username, reset the OwnerGuid back to 0, save the file, and start the server. The server will authenticate the new owner the next time they join the universe.
