I agree, also not really a big fan from the facebook login.
In the past I used always facebook login, was really comfortable, but anywhen i got banned (I have to note, i played really active specific facebook games and to get far in these games, you needed much friends and well I did make many request, but looks like some of these pressed “I dont know that guy” button and so facebook banned me, which was totally idiotic -_-" because facebook allows these games, but not that you add people you dont know, it is written in their rulebook, you are only allowed to add people you know in rl
)
TL;DR; if you get banned on facebook, all your accounts which are created by facebook login, wont work anymore
nice or?
so I rather like to connect it by steam or at least with twitter, because I know i wont be banned by it
