What is Knock?

Knock is an innovative utility designed to streamline the way users interact with and secure their Mac computers. Developed to eliminate the friction of typing passwords, it allows users to unlock their devices by simply tapping on their iPhone or Apple Watch. The tool leverages Bluetooth Low Energy to maintain a secure, low-power connection between devices, ensuring that the Mac only unlocks when the authorized mobile device is in close proximity. Beyond simple unlocking, Knock provides a seamless way to manage system access without compromising security or speed. It is particularly well-suited for professionals who frequently step away from their desks and want a hands-free, modern authentication experience. By turning a smartphone into a physical key, Knock bridges the gap between mobile convenience and desktop security. It fits perfectly into the workflow of anyone looking to modernize their hardware security through simple physical gestures.
