Keycard: Unlock your Mac using an iOS device

Keycard allows you to pair your iPhone or other Bluetooth enabled device with your Mac to lock and unlock your computer.

It detects when you’re leaving your desk, office, or room and automatically locks your computer to ensure it’s safe and secure. When you come back it unlocks—magically.

Keycard is built for you to be able to have your own custom 4-digit pin as a fail safe. Say you don’t have your device on you or maybe it’s dead, lost, or stolen.
