How to add a Steam Auth Token to your Unturned Server

Unturned uses a Steam Game Server Login Token, often shortened to GSLT or Steam Auth Token. Add the token to Config.json, then restart the server so Steam can authenticate it.

Before you start

• Create a Steam Game Server Login Token for Unturned if you do not already have one: Steam game server account management.
• Keep the token private. Treat it like a password.
• Stop the server before editing the config.

Add the token

1. Open your Unturned server in the control panel.
2. Open Configuration Files.
3. Open Config.json with Text Editor or Config Editor.
4. Find "Login_Token": "".
5. Paste your token between the quote marks.
6. Save the file.
7. Start or restart the server.
8. Check the console or log viewer for Steam authentication errors.

Example

{
  "Browser": {
    "Login_Token": "YOUR_STEAM_TOKEN_HERE"
  }
}

Your live Config.json may contain more settings. Keep the surrounding JSON valid and only replace the token value.

Troubleshooting

• If the server still asks for a token, confirm the JSON saved and the token is inside the quote marks.
• If the server fails to start, check for a missing comma or broken JSON formatting.
• If the token is rejected by Steam, generate a fresh token and replace the old one.
• The Unturned console may warn that the server cannot be joined over the Internet when no GSLT is set.
