How to whitelist a Valheim server?

Tired of sharing the password every time? Switch to a whitelist on your Valheim server and only let approved players in. It’s fast, clean, and secure.

Prerequisites

• Access to your Oxygenserv panel (login and password)
• An installed Valheim server visible in the panel
• Players’ Steam profile links or their SteamID64 (17 digits)
• Basic use of the file manager (open, edit, save)
• Optional: quick backup before editing

Step-by-step

1. Log in and gracefully stop the server
   Open the Oxygenserv panel and select your Valheim server. Go to the Console and click “Stop”. Wait for logs like “Shutting down” and “Server closed” before proceeding. This prevents the game from overwriting files while you edit.
2. Open or create the whitelist file
   Go to Files (File Manager). In the server root, locate permittedlist.txt. If it’s missing, create it (“New file”) and name it exactly permittedlist.txt. Depending on setups it can also live in the saves folder; on Oxygenserv it’s exposed at the service root for convenience.
3. Get each player’s SteamID64
   Ask players for their Steam profile link (e.g., https://steamcommunity.com/id/alias). Paste it into a converter (e.g., steamid.io) and copy the steamID64 value (17 digits). Valid example: 76561198000000000. Do not use nickname, Friend Code, or SteamID32/3 formats.
4. Add the IDs, one per line, no extra spaces
   In permittedlist.txt, put exactly one SteamID64 per line. Example:
   76561198000000000
76561199012345678
   No commas, no comments. Click “Save” (green button) when done. If you see trailing spaces, remove them.
5. Restart and verify access
   Go back to Console and click the green “Restart” button. Watch the logs: when an allowed player connects you’ll see “Got connection SteamId 7656…” without a rejection. Non-listed players will be refused; logs may show a kick/deny message. If no one can connect, check every ID has 17 digits and the file name is exactly permittedlist.txt.

Tips & optimization

– Use whitelist + password for layered security. Whitelist controls “who”, password protects even if an ID leaks.
– Keep a local list of staff/regulars’ SteamID64 to reapply after reinstalls.
– Also leverage bannedlist.txt to block griefers and adminlist.txt to grant admin rights.
– If you edit the list frequently, restart during off-hours to avoid interrupting runs.
– If changes don’t apply, you probably edited the wrong permittedlist.txt. Double-check you’re on the active instance.

FAQ

Where is the permittedlist.txt file located?

On Oxygenserv, it’s available from the Files tab at the server root. If it’s missing, create it as permittedlist.txt. If you run multiple instances, ensure you’re editing the one that’s actually running.

A whitelisted player still gets a password prompt. Is that normal?

Yes. The whitelist decides who may enter; the password is still requested if you set one. Keep the password as a second barrier. Removing it isn’t recommended for public servers.

I added a nickname instead of an ID. Will it work?

No. Valheim requires a 17-digit SteamID64. Use a converter (steamid.io) from the Steam profile link, copy the steamID64, and replace the wrong entry.

Do I have to restart after editing?

Changes can apply right after saving, but a quick restart guarantees a clean reload. If an allowed player is still denied, restart and try again.
