Tognazzini Suggests Using A Smartwatch To Replace Unlock Passcodes As An Authorisation Mechanism
So you have to the inconvenience of carrying another device with you in order to have the convenience of PIN-less entry? Doesn’t seem worth the effort. It’s not just the burden of carrying another thing. Inevitably, a smartwatch would need maintenance, be that charging, updating, and other similar procedures.
If Apple is going to eliminate the passcode successfully, it needs to be built-in to the phone hardware. Fingerprint biometrics seem like a more practical, elegant and realistic solution.
