I guess since writing that email, I would have preferred the option of taking a photo (and not storing it anywhere except here). You get used to system dialogs "looking like this" with the photo. If something is wrong, most humans pick it up easily. Only for blind users do you need the text.

With the hundreds of password dialogs that you get in iOS for various reasons, I think people would catch on pretty quickly to a new secure variant.

Yeah, some people wouldn't, but that isn't a reason to leave it with the terrible implementation they have now. This has annoyed me since forever on iOS.

I mean this flaw has been known for years. How long have we been pressing ctrl-alt-delete to log in to Windows?
