does touchid have the disadvantage of keeping your friends and family unable to use your phone in cases of emergency? 95% of the time, my phone isnt next to adversaries, but trusted parties. a password or code is transferrable, fingerprint isnt.
edit; not 911emergency, but casual situations of full or dirty hands..
You can always just use a PIN to unlock. It's probably safe to assume that Apple has thought this through (no need to remind me of the supposed chaos break-in).
You can add ten fingers, or you can give them your code, or they can dial 911 with a fully locked phone. So no, it's slightly easier for a relative to use in an emergency than a typical locked phone.
Mine when locked has a small touch section labeled 'emergency call'. I assume it goes through to 911 (or relevant number). I'm tempted to press it but it's not an emergency.
I assumed most phones had something similar.
Edit:
I went to it. I leads to a special dialer. Instead of voicemail the button leads to a special emergency contact (or list). It only shows 4 inputs on top so I am guessing that is the limit so you can't dial anything but emergency services (that are 4 numbers or shorter). Then it goes back to my lock screen.
