Registering your server with Valve

  3. Once generated and you've got your token go to configuration files in the control panel. 
  4. Click text editor to the right of your server.cfg file 
  5. Add a new line with sv_setsteamaccount "your-generated-token-here" and then Click save. 
  6. Restart your server and you are now done.
