Learn how to authenticate game servers with the Steam GSLT for public listings and VAC protection → Find out more now
The GSLT (Game Server Login Token) is a login token issued by Steam/Valve required to run dedicated servers for certain games. It is linked to a Steam account and ensures the server is properly authenticated.
Without a valid GSLT, affected servers may not appear in the public server list or be able to use VAC protection.

To use a Game Server Login Token (GSLT), your Steam account must not be restricted, banned, or community banned. It must be linked to a verified smartphone, and you must own the game you want to host. You can create up to 1000 tokens per account.
Note that you are fully responsible for your tokens. If a token is abused or banned, you may permanently lose access to the linked game. Never share your tokens, and if you do, delete them immediately. If your Steam password is reset, all tokens are automatically regenerated. Tokens that remain unused for a long time expire but can be recreated at any time.
To create a Game Server Login Token, log in with your Steam account and visit the Steam Game Server Account Management page.
After logging in, you can create a new token using the form on the page. In the App ID field, enter the App ID 550, which belongs to Left 4 Dead 2. Make sure to enter the correct ID, as the token will not work with an incorrect value.
In the Memo field, you can add a description of your choice. This helps you later identify the token’s purpose, e.g., the server’s name or role. After entering both values, click Create to generate the token. The token will then be displayed and can be used in your server’s startup configuration.
The login token must now be entered into your server configuration. Open your game server’s management interface and navigate to the Configuration tab. Enter the token in the GSL Token field and save the changes.
Running Multiple Left 4 Dead 2 Servers If you run multiple Left 4 Dead 2 servers, you need a separate GSLT for each server. It is not possible to run multiple game servers with a single GSLT.
The GSLT has been created and entered into your server configuration. If you have any further questions or need assistance, our support team is available daily! 🙂
