Embodiments of the claimed subject matter provide a method and an apparatus for enabling delegated authentication for web services. Delegated authentication is provided without divulging the information the user requires to complete an authorization procedure of another web service or otherwise subjecting the user to unnecessary risk. Furthermore, delegated authentication is granted for a limited duration and access is subject to further limitations to prevent unnecessary intrusion to the user, the user's data, and the host web service. One embodiment of the claimed subject matter is implemented as a method for enabling delegated authentication to allow a third party service access to protected data on a host service. A user attempting to utilize functionality of a third party website that requests access to the user's data stored on a separate host website is enabled as a delegate with authorization to access the data stored on the host website.
