App developers rarely spend time authenticating user sign-ins anymore. Facebook (NASDAQ:FB) made the need to do so all but irrelevant five years ago when it unveiled Facebook Connect for the iPhone.

Today, the social network is awash in data from users signing into any number of on-the-go apps using their Facebook credentials. Twitter benefits from this same dynamic, but on a smaller scale. Now Google (NASDAQ:GOOGL) wants a piece of the action. The search king introduced a plan to allow users to sign into apps using a Google+ account.

Should Facebook shareholders be concerned with Google's grab for a bigger share of the data produced by mobile users?
