Tired of typing in countless passwords to log in to your Mac? Well if you own an iPhone (and frankly, if you’ve got a Mac you’ll probably have an iPhone too) then there’s a new and rather interesting way to get into your Mac.
The Knock app allows you to log in to your Mac by knocking on your iPhone. Yes, you heard that right – just two simple knocks and your computer automatically unlocks. Once the app is installed on your iPhone and Mac, the phone will prompt you when it detects your Mac nearby. The system works via Bluetooth Low-Energy, so it doesn’t drain your phone battery. As long as the app is running in the background of your iPhone and your Mac is nearby, you’ll be able to unlock it simply by knocking on your iPhone.
The app is currently available in the App Store for $3.99.
