Technically, this could/should have been already solved with voice authentication. Nuance and other companies have been claiming/pushing it for a few years now: http://www.nuance.com/for-business/customer-service-solution.... I'd actually expect Apple to be the first big player to incorporate that, as they've been a leader in accessibility. Maybe somebody should sue them for discrimination to accelerate the process.
Yeah, I've been using voice dictation software since I became quadriplegic over a decade ago and they were talking about it then but it's not materialised yet. I would imagine that it's going to be Apple there's going to be first in this area, but I'm not convinced they're going to do it for accessibility reasons, I think they're going to do it for payment/password reasons. Which if I get the trickle-down benefits from then, go Apple!
I assume they dropped it because it wasn't actually secure, I remember my brother getting past mine once with only a couple of tries.
Presumably we could do better today, but as far as biometrics go, I'd put my money on Windows Hello's facial recognition over voice showing up again. Apparently they've done a better job of it than the Android handsets a couple years ago managed.
