Doesn't this just reinforce the fact that using a third-party service for authentication is a bad idea? Most users don't understand it. You app is, generally, forced to ask for more permissions than desired. And you are at the mercy of the third party. I don't see any way in which a third party authentication service is a win.

It's a win because users aren't forced to go through the typical create username/password --> email verification --> sign in flow. Is it worth it to the end user? Maybe, maybe not. But it saves them time, and there's lots of empirical evidence that sign-up rates are drastically higher with social login.

Where? I've never seen any evidence at all, just claims from social marketing weasels. The only empirical evidence I've seen shows it doesn't help at all, and that the majority of users don't like it.
