To give your American Truck Simulator server a fixed Steam identity, create a game server login token on Steam’s game server page with app ID 270880 (the game, not the server), paste it into Steam Auth token on Startup in the Game Panel and restart. Without a token the console shows [MP] LogOn Anonymous and the server gets a new, non-persistent ID on every start.

​
Before you start

  • You need a Steam account that owns American Truck Simulator. Steam requires game ownership to create the token.
  • Steam may have other account requirements for creating tokens; its page tells you if one applies.

​
How to create the token on Steam

1

Open Steam's game server page

Go to steamcommunity.com/dev/managegameservers and log in.
2

Enter the app ID

Enter 270880, the app ID of American Truck Simulator. Don’t use the dedicated server’s app ID (2239530); SCS says to use the game’s.
3

Add a memo and create

Type a memo, for example FREAKHOSTING ATS server, and create the token. Copy the login token.

​
How to add the token to your server

1

Open Startup

In the Game Panel, open your server and click Startup.
2

Paste the token

Paste it into Steam Auth token (up to 32 characters), then click outside the field. It saves automatically.
3

Restart

Restart the server. The panel writes the token into server_logon_token in server_config.sii on every start.
4

Check the console

The [MP] LogOn Anonymous line should be gone from the console.

​
Why use a logon token?

A fixed ID matters when players use direct search: they keep the same search ID instead of needing a new one after each restart.

​
Frequently asked questions

​
Do I have to use a token?

No. The server runs without one. You only lose the persistent server ID.

​
Can I use one token on two servers?

No. SCS says the logon token must be unique for each running server. Create one token per server.

​
Should I put the token in server_config.sii?

No. Use Steam Auth token on Startup. The panel overwrites server_logon_token in the file on every start.

​
Is the token secret?

Treat it like a password. Anyone with it can run a server under your Steam game server account. If it leaks, regenerate it on the Steam page and paste the new one.
