I need to embed password protected content to a second domain with an iframe. The content itself is a view which will be displayed on a third party site via an iframe and the content is prepared with a custom page and template handing the display. The use case is to present the view on the other site without the users needing to login. From my research, Oauth or Services seem like good candidates, but I don't have much experience with both and using a service to show a single view seems like it might be an over complication. Anyway, I haven't found much in the way of good documentation on the subject so I'm hoping for a good introductory overview of how to implement this. So, what is the best way to securely authenticate the drupal content on another site. I don't want to expose user credentials in the src=url in the frame for security purposes, so I know I need to use another authorisation mechanism. I've looked at the Entity Iframe module, which seems to have some of these features but the module mainly works drupal-to-drupal, and I haven't been able to tangle apart how the module handles the consumer/provider communication.
So, from researching this, I believe that I have to configure oauth and pass the token to the URL in the iframe. What I am unclear about is how to configure oauth access to the page and how to generate the token to be supplied to the iframe.
