Set Up a Valheim Server Whitelist

Why Use a Valheim Whitelist

A Valheim server password is useful, but it is not always enough if the password gets shared around. A whitelist adds a stricter gate by allowing only specific Steam accounts to connect. Anyone missing from the list stays outside the mead hall, even if they know the password.

This is helpful when you are building a private world, testing changes before inviting friends, or keeping the server limited to a trusted group.

Find the Player SteamID64

Before editing the whitelist, collect the SteamID64 for each player you want to allow.

1. Go to the SteamID.io website.
2. Search for the player's Steam profile name or profile URL.
3. Open the matching result.
4. Copy the SteamID64 value.

Repeat this for every player who should be able to join.

Add Players to permittedlist.txt

Once you have the SteamID64 numbers ready, update the Valheim whitelist file.

1. Open your server panel.
2. Stop the Valheim server before changing files.
3. Open the file manager or FTP client from your panel.
4. Find `permittedlist.txt` and choose the edit option.

Add one SteamID64 per line. Do not place commas, spaces between IDs, or extra notes on the same line. The file should stay plain and boring, which is exactly how server config files like to live.

After adding the IDs, save the file and return to the main server page. Start the server again so Valheim reloads the whitelist.

Managing the Whitelist Later

To add another player, place their SteamID64 on a new line in `permittedlist.txt`, save, and restart the server. To remove access, delete that player's SteamID64 from the file and restart again.

After the restart finishes, only players listed in `permittedlist.txt` should be able to connect to the Valheim server.
