It covers building HtmlHelper extension methods for embedding or linking to the RPX login widget, writing an RpxLogin class that posts a token to RPX's auth_info API and deserializes the JSON response, and wiring everything into an AccountController with Login and Logout actions using FormsAuthentication. Sample code is provided as a downloadable zip. ## Full article daily.dev links to this article rather than hosting it.
