Set up your Valheim dedicated server

Valheim configures its dedicated server through start parameters, not a config file. Set the name, world, password and visibility, and add admins by Steam ID.

Start parameters

  1. -name sets the name shown in the browser.
  2. -world sets the save to load or create.
  3. -password must be at least 5 characters and cannot be contained in the server name.
  4. -public 1 lists the server in the community browser; -public 0 is friends/direct only.
  5. Add -crossplay to enable PlayStation/Xbox/PC crossplay through the PlayFab network.
ImportantA public server (-public 1) must have a valid password (5+ characters, not part of the name) or it will refuse to advertise.

Admins and the world files

  1. Add trusted players to adminlist.txt using their Steam ID, one per line.
  2. A world is a matched .db and .fwl pair in the worlds_local folder — back up or move both together, never just one.
