‘Knock’ Lets You Securely Unlock Your Mac By Pounding Your iPhone Screen

Typing in your password every time you want to unlock your Mac sucks. Apple still hasn’t added facial ID recognition to OS X, nor have we heard nary a mention of Touch ID coming to MacBooks, but if you’re looking for a neat way to quickly unlock your Mac, a new app called Knock allows you do it with two quick taps on your iPhone screen.

The free Mac app works in tandem with an iPhone app that turns your phone into an authentication device. Knock uses Bluetooth Low Energy to communicate from iPhone to Mac but you should be able to leave it on all day without draining battery.

Here’s a video of Knock in action:

Because Knock requires Bluetooth 4.0 it only works on the iPhone 4s, 5, 5c and 5s and the following Macs:

  • 2011 MacBook Air or newer
  • 2012 MacBook Pro or newer
  • 2012 iMac or newer
  • 2011 Mac mini or newer
  • 2013 Mac Pro

The Knock for Mac is a free download but the iPhone app will cost you $3.99.
