I don't suppose you could sly it? Make it look like your finger?
Anyway, my point isn't that touch-ID is insecure. I'm just having a hard time seeing how it is any more secure than a good password. Nobody can chop my password off, nobody can use it on the sly when I'm asleep, nodody has anyway of knowing what it is unless I leave post-it-notes around with it written down.
You're just being insane.
I GUARANTEE if somebody was in front of you with garden shears threatening to chop off your finger; you'd give up your password instead in a jiffy!!!
Also, TouchID doesn't work & I have to resort to password every time I come in from the cold, or if my hands are wet- it's a bit finicky. Lol, not sure it'd work with a cold & pulseless corpse finger...
Then, I might note that there a LOT more petty thieves in the world than heartless cold maiming finger severers!!! Lol, as a matter of fact I've NEVER heard of that. The idea of a thief snatching a debit card or phone is that it's a teeny crime... & easy. They only get a few hundred dollars, tops & if they get caught they'd get a small slap on the wrist. The prison system is not full of cell phone thieves.
However, there would legitimately be a manhunt for a psychopath that was chopping off fingers to make a few dollars.
What reality have you concocted where the stuff your saying sounds remotely plausible??!!
