Google Identity Toolkit

Google Identity Toolkit (GIT) helps relying party (RP) websites to support federated login easily (http://code.google.com/apis/identitytoolkit).

This is the GIT plugin for OpenCart 1.4.x, 1.5.x to help website owners to integrate GIT into their websites. It provides Google Account Chooser widget, which allows users to login with their email address and password, and would like to replace that password with federated login. It currently supports Google mail, Hotmail, Yahoo! mail, AOL mail, and Google Apps mail but more identity providers will be added in the future. Other companies that are members of the OpenID Foundation offer similar functionality including Janrain, Microsoft, and Ping Identity.

If you finished integrating this plugin with your website, please give us some feedback to improve the ease of integration. We may contact with you for any announcement related to Google Identity Toolkit Plugin in the future.
