‘Google Gives Developers More Ways to Incorporate Google+’ – ‘Mashable’

Emily Price says, “Late last month, Google gave developers the ability to add Google+ sign-ins to their sites, and the company expanded that feature on Tuesday, giving developers more options to go along with it.

Google+ sign-ins are similar to their Facebook and Twitter counterparts, allowing users to sign in to a website that isn’t Google-owned using their Google credentials, bringing along information from their Google+ profile such as their name and friends”.
