A sequence diagram showing a secure authentication flow between a User, Browser, Auth Server, and Game Server. The process begins with the User entering credentials into the Browser, which sends a POST request to the Auth Server. The Auth Server returns a "Set-Cookie auth token" to the Browser. The Browser then sends a "Join game with cookie" request to the Game Server. The Game Server validates the session with the Auth Server, receives a "Valid user ID," and confirms "Game joined" back to the Browser. A highlighted note at the bottom emphasizes: "Cookie never accessible to JavaScript."
