Google hasn't had too much success yet with Google+ compared to the runaway success of competitors like Facebook and Twitter, but one thing that's certain is that the search giant is NOT just sitting around hoping it'll get better.
Today, they've unveiled a major update called Google+ Sign-In, which offers 'simple, secure authentication' via Google IDs all over the web. It works similar to Facebook Connect, but using Google's sign-in features automatically links it to folks' Google+, Gmail, etc. accounts that offer high security options like 2-step verification and more.
Will this help engagement with the social network as well? We'll find out. In the meantime, here's the details from the Google+ Developer's blog.
Seeking an easier way to grow users with hassle-free, one-click sign-in? Google+ Sign-In increases conversions by reducing the burden and friction of login-particularly for mobile users-all while helping users keep their accounts more safe.
With minimal effort, you can add a trusted registration system that's familiar to users and consistent across devices. Google+ Sign-In lets users skip high drop-off registration forms and avoid having to remember yet another username and password. This makes registration faster and more secure, and reduces support costs for forgotten usernames and passwords.
