Secure identity provider authentication for native application to access web service
A native application on a client computing device enables secure user authentication via an identity provider (IdP) for accessing services of a web service provider. The native application forwards a redirect request generated by a main gateway of the service provider and including an IdP uniform resource locator (URL) to a system browser of the client computing device. The redirect request directs the system browser to a broker gateway of the service provider that registers an authentication response handler and redirects the system browser to the IdP URL to enable a user of the native client computing device to authenticate. After the broker gateway receives an IdP authentication response from the IdP following authentication by the user, the broker gateway provides the IdP authentication response to the native application for providing back to the main gateway. The main gateway finally processes the authentication response to complete the authentication request. |
