I'm trying to make login. And I think only google account login is enough for my game. Don't have guest login thing. But I saw the best practice that do silent login first and then link the google account with that already silently logined playfab account.
So, I got some questions.
Should I always use android deviceID login first? (using android_id)
If I use only the google account login process for my android game, there would be any cons, like that I wouldn't be able to use some Playfab features? And would the users be able to login to my game from mutilple devices using the same google account?
