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.
As we explained in our original post about Knock way back in 2013, the app works by pairing your iPhone to your Mac over Bluetooth low-energy. Instead of typing in a password to unlock your Mac, you just rap on the screen within range, and your Mac unlocks.
With the latest update to the Knock for iPhone app, you can now do the same thing from your watch face.
You keep your iPhone with you all the time. Now you can use it as a password. You never even have to open the app — just knock on your phone twice, even when it’s in your pocket, and you’re in. And if you have an Apple Watch, you can unlock your Mac right from your wrist.
There’s even an extra security feature called Touch To Unlock that requires Touch ID on your iPhone to unlock your Mac, if you want to enable it.
Knock is available on the iTunes App Store for $4.99
