This flow, recommended by the plugin, utilizes the system’s default browser to run the OpenID or OAuth2 flow. This approach allows your game to trigger the opening of the browser as a separate application, where the user can complete the necessary steps. Once complete, the browser will send back the required information to the game. This flow provides a seamless user experience and ensures the security of the user’s information.
