Social Auth Google

This project is part of the Drupal Social Initiative and is based on the Social API.

Social Auth Google allows users to register and login to your Drupal site with their Google account. The module allows websites to request any scopes, so any tasks requiring authentication with Google services can be performed. This module is based on Social Auth and Social API projects.

This module adds a path user/login/google which redirects the user to Google Accounts for authentication.

After Google has returned the user to your site, the module compares the user id or email address provided by Google. If the user has previously registered using Google or your site already has an account with the same email address, the user is logged in. If not, a new user account is created. Also, a Google account can be associated with an authenticated user.

Login process can be initiated from the "Google" button in the Social Auth block. Alternatively, site builders can place (and theme) a link to user/login/google wherever on the site.
