As a third party web application developer, you may know about AuthSub, an authentication proxy service bundled with the Google Data APIs. AuthSub gives you access to service data protected by a user's Google account without your web application ever having to handle usernames and passwords. We are excited to announce that AuthSub has now been extended to support Google Apps accounts as well!
Google Apps brings together essential services to help businesses, schools, groups or families communicate and collaborate more effectively. A large and growing number of organizations are choosing Google Apps, including more than 500,000 businesses and thousands of Universities. With our latest release of AuthSub, you do not need to make any code changes to reach these Google Apps users. As part of the AuthSub flow, users are directed to a sign-in page where they can choose to grant you access to either their Google account or to their Google Apps account. You can choose to customize this default behavior by making minor code changes, a handy option if, for example, you are developing applications for one particular managed domain. For details on the new authentication flow and customization options, please see our documentation.
AuthSub helps keep accounts secure by making it possible to share certain information from those accounts without sharing the username and password that protect them. We hope you and your Google Apps users will enjoy the added protection.
