Valheim console commands

Sets which world the server loads. A new world with that name is created if it does not exist.

Sets whether the server is listed in the public server browser: 1 to show it, 0 to hide it.

Runs the server on the crossplay backend (PlayFab) so players on any platform can join, with no port forwarding needed.

Sets the world modifier preset, such as casual, hard or hardcore, overwriting earlier modifiers.

Sets one world modifier, like combat, raids or portals, to a chosen value.

Removes a player from the server right away. They can rejoin unless you ban them.

Blocks a player from the server so they cannot rejoin, saved in bannedlist.txt.

Sets the interval between the later automatic backups, in seconds. The default is 43200 (12 hours).

Sets the interval for the first automatic backup, in seconds. The default is 7200 (2 hours).

Sets the file path where the server writes its log.

Sets the server name shown in the in-game server list.

Sets the password players must enter to join the server.

Sets the folder where worlds and the admin, ban and permitted lists are saved, replacing the default path.

Sets how often the world is saved, in seconds. The default is 1800 (30 minutes).
