This is all familiar, but more detailed than I'd read before. Thank you! Most of my background on this topic was gleaned through working on the authentication application through my previous employer. I really don't know the history of systems security.
dilettante, below, proffers a fourth kind of secret that compasses unique physical skills/motions/behaviors (like the WWII "fist"). It wasn't cost-friendly, nor certain, to use the "fist" to authenticate the apps I was working on, but our research did make me wonder. Some day maybe we'll add "what I do" to the list. :)
Even a unique, individuated Personal Turing Test wouldn't solve for the "man in the middle" scenario, though. Hm.
