I'm using lock v11.7.2 on hosted login page. I observed that authenticated event is not fired after login successfully, it just redirect to the callback URL.
The authenticated event is only emitted when the authentication token is successfully parsed. The hash parsing never happens inside the hosted login page, so it can't possibly emit that event.
