Google has announced application sign-in and some other  related enhancements for Google+. It is similar to logging on to websites with your Facebook and Twitter IDs. Google seems to have arrived late to the game.

Currently there are only 10 developers committed to using Google+ sign-ins. They include Guardian, Shazam, Fitbit and Fancy and USA Today.

“If you sign in to Gmail, YouTube or any other Google service, you can now use your existing credentials to sign in to apps outside of Google,” Google explained.

“Just review the Google+ permissions screen (outlining the data you’re sharing with the app, and the people who can see your activity), and you’re all set,” it added.

“Many developers offer web and mobile versions of their app, yet setting things up across a browser, phone and tablet is still a major hassle. Starting today, when you sign in to a website with Google, you can install its mobile app on your Android device with a single click,” Google wrote.
