Leash - Proximity lock

Leash keeps your computer secure by locking it automatically when you step away — using the Bluetooth signal of your iPhone, Apple Watch, or AirPods.

No passwords to type. No buttons to press. Just walk away, and your computer locks itself.

HOW IT WORKS
Leash continuously monitors the Bluetooth signal strength of your paired devices. When your device moves out of range, Leash waits a few seconds and locks your Mac automatically. When you come back, simply unlock as usual.
