Remember Knock? Released last year, it was an iPhone app that allowed you to unlock your Mac without entering a password, just by tapping on your smartphone’s screen. Now you don’t even need your iPhone handy to use Knock: It’s the latest app to get the inevitable Apple Watch support.
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.
