Google has just announced the introduction of the Google Plus Sign-In, a new feature of the Google Plus platform that allows developers using the Google Plus API to add a secure sign-in to their web and mobile applications.

The new Google Sign-In feature is being rolled out gradually, however it is currently available on several websites including Fitbit, Flixster, The Guardian, and USA Today.
