How to set Valheim server permitted players

You can “whitelist” certain players to be allowed into your world.

If you make any use of this functionality, all players not on the list will be rejected from entering the world.

Steps

1. Note down the SteamID64 (Dec) of the user(s). You can find this value here if you don’t know it, and it is also shown along with the users name in-game, if you press F2.

2. Add the SteamID64 (Dec) values to the permittedlist.txt file on the server machine, one per line.

   The permittedlist.txt file is located in the same directory that Valheim uses to save the worlds/ directory that stores world save information.

   By default this location is:

   Windows: %USERPROFILE%/AppData/LocalLow/IronGate/Valheim/

   Linux: ~/.config/unity3d/IronGate/Valheim/

   The file should end up looking something like this:

    // List permitted players ID ONE per line
    76521191055385553
    76551295065884553
    77556392054375653
   

   Note: do not add any other text to this file, comments after ID numbers or similar.

3. When you have updated the permittedlist.txt file, the changes should apply immediately, but if you have issues, try restarting the server.
