for the time being only via facebook, we are considering our own user login and other alternatives too...stay tunned
nice )
You can also make sign up with google

Yes please! I've been lately using twitter and google logins and found out they provide a great user experience - as long as I don't have to reenter my details or use them as basis to create an account...
same here, facebook is the new digital id.. cant keep track of dozens of password for every site...
Actually, the reason I'm not closing my facebook account is just to use login everywhere. Besides that, i don't use it at all. So i would appreciate login with facebook or etc.
I would prefere an login not through facebook or something else. I hate that facebook etc is all over and gets all your data here, what you are using etc etc. On the other side I also don't like that other apps get all the information through facebook about me.
you can remove those apps from your apps settings. In my opinion its more convenient ..
