Is there any other way for yahoo login API authentication other than using the website. We are building an Application for Iphone and wanted to have users login within our iphone application without going through yahoo browser based authentication .

Your help and direction will be greatly appreciated.

Hi Sam,

We don't have public API for authentication other than through
the Web browser:
http://developer.yahoo.com/auth/

I think a workaround is to establish some inter-processing
communication channels between your application and the mobile
phone's Web browser.
