Yahoo has released application-building technology which will give businesses access to the company's single sign-on system - covering 200 million people with Yahoo! accounts.
The release of the Browser Based Authentication system means businesses can create websites that do not require users to set up a new username and password, but will instead authenticate Yahoo! users.
The technology includes a security feature which means that users’ Yahoo! IDs are not shared with the third-party applications. Instead, the user is redirected to a Yahoo! login page, which then generates a unique encrypted ID that is sent back to the application.
An announcement on the Yahoo! developer network website adds that the technology is “still fairly experimental” and the company is seeking feedback from developers.
