To enable Pre-Authenticated Login for your web store:
  1. Create a URL in the following format to send players from your game to the web store: https://your-web-store/login?proofKey=<value>&token=<value>, where:
    • proofKey: The player code.
    • token: The access token.
  2. In the Publisher Dashboard:
    • Go to Settings → Authentication.
    • Scroll to the OTP section and toggle it on.
    • Leave the Initiate Game Auth API field empty, unless you also plan on implementing Game Redirect Login.
    • Use the Desktop Text Model dropdown to choose how many digits your player code will have (4 or 6).
      This setting applies to both the Pre-Authenticated Login and the Game Redirect Login methods. If you plan to implement both methods, you must use the same number of digits for your player code across both.
