Found this last night. Its the closet ive come to being able to generate keys the way i've described but it uses an email address instead of a password.

There used to be different tabs you could select, if you want movies could search for movies, if you want games, search for games, if you wanted documents serach for documents etc. I'll have a quick look now & see if its still possible.
