OAuth which is a privacy controlling open web authentication standard, has been adopted by Google for its widget platform Google Gadgets. OAuth provides a way for users to authenticate a website on which their personal information is stored so that they can share the data on other website or widget. According to Google’s senior product manager for security, Eric Sachs:
We also previously announced that third-party developers can build their own iGoogle gadgets that access the OAuth-enabled APIs for Google applications such as Calendar, Picasa, and Docs. In fact, since both the gadget platform and OAuth technology are open standards, we are working to help other companies who run services similar to iGoogle to enhance them with support for these standards.
