By default, by login in with Google or Facebook you can assign to that user his name from the service that is using (google or facebook) but with FirebaseAuth once you are logged in you can display any sort of dialog requesting the user to complete a certain profile with data, name, birth date and more, and then just store that data inside that userID that is generated with Google-Facebook sign in and display that data to the user.
