Google Powers Up Google+ Social Sign-in
Google will now allow users to sign in to third-party apps using their Google+ log-in, the company said on Tuesday. Once logged in this way, users will be prompted to specify with which Google+ circles they want to share content. The log-in blocks the so-called “frictionless sharing” that Facebook introduced in early open-graph releases, inviting harsh criticism from users and privacy advocates. “Google+ doesn’t let apps spray ‘frictionless’ updates all over the stream, so app activity will only appear when it’s relevant (like when you’re actually looking for it),” wrote Seth Sternberg, director of product management for Google+.
