During and after yesterday’s Apple announcement of its FaceID unlocking feature for its new iPhone X, some brief discourse began on the Ars #staff Slack channel concerning legal rights when your face is your new passcode. It’s a big deal, as this is the future of smartphone unlocking—largely because Apple says so.
