Yeah, I agree that it would be hard for the authenticating side to do much, mainly because it's hard for them to tell if the app is doing something untoward. I wonder if triggering DOM keypress events gets propagated up to external webview code and you could set some honeypots or steganography... hmm. I'm sorry but I'm still very new to thinking about this problem space. > > Nobody dismisses the problem you're talking about, it's definitely a > problem.

At this point, it would be just nice for the industry to know that the issue even *exists*. Hence my puzzlement at the overt hostility from some quarters. > > I personally want OAuth 2.0 to get out the door.

I was just very puzzled by the lack of discussion about the lack of applicability of the protocol in either the protocol document or in the threats. It made me wonder whether this scenario had even been considered. I'm still not sure if it had been. > If you really think you've got something here, draft language and > propose it.

That should be part of the abstract and introduction, IMO. Mike
