Many websites, apps and services make use of authentication platforms that are provided by third parties such as Facebook or Twitter. Facebook Connect or Twitter Login offer several advantages over first party sign in technologies. Sign-ups do not take this long after all, it is usually not required to verify an email address or phone number, and the service or app a user creates an account for does not store the user's password in its database. While comfortable most of the times, some users dislike the privacy implications as information are shared between the application sign in platform and the app or web service.
Google today announced the launch of Google+ Sign-In, a platform by Google that makes available similar authentication options for apps or web services. The platform on the user side of things works very similar to Facebook Connect and other authentication platforms.
Websites and apps present an option to log in with Google instead of signing up or logging in with an account that needs to be created on site by the user. The example above highlights how Fitbit makes use of Google's new authentication platform on the company's login page.
When you use Google+ sign-in for the first time on a site, you are presented with a permissions screen that details what the application would like to get permissions for. Next to each item is an icon that you can click on to display additional detailed information about the permissions.
Some items can be modified on the permissions configuration page. In this case, it is possible to remove the permission to access users you are connected to on Google+, and to block the app from informing people in your circles that you have just signed up for that service.
Google users who make use of the new sign-in platform find a manage apps page on Google+ that they can use to edit the visibility of apps, disconnect the app from the Google account, view the application's activity, or delete all activities.
According to Google, the company has focused on four key principles for this initial release of the platform:
