Lock Your Mac With Knock, Unlock With iPhone
A new app and Mac program called Knock will allow you to unlock your computer via a “Knock” on your iPhone.
The software is also a mobile app that will allow you to unlock your computer.
This works by having the Knock app on your Mac and on your iPhone simultaneously. The beautiful part about it is that it’s so much easier to “knock” on your iPhone than it is to type out an entire password.
This could result in a new line of “password” apps that add an additional lay of security to locking your Mac computers.
