Are you tired of entering your password to unlock your Mac? Or do you even forego setting up a password for your Mac to avoid the hassle of unlocking it? If you’re like me and tend to carry your iPhone with you everywhere, developer Knock Software released today a unique solution to unlock your Mac using a simple gesture and your iPhone and doesn’t require you to touch your keyboard.
With Knock installed on your iPhone, along with the free companion app for your Mac, all you need to do is knock twice on your iPhone to unlock your Mac. Sounds crazy easy, right? It is and it does work. Here’s a cute promo video for it:
How does it work? The answer is through the magic of Bluetooth Low Energy, a Bluetooth protocol present in Apple’s newest Macs and iOS devices. Through Bluetooth and the Knock app, your Mac will recognize when your iPhone is nearby. When you knock on your iPhone, this signals to Knock to unlock your Mac and it enters your password on your behalf. It works even if your iPhone itself is locked and is in your purse or pocket.
Setting up Knock is easy and the apps will walk you through the process which takes a minute or two. Once you’ve got it set up, Knock will remain active in your Mac’s menu bar to detect your iPhone and enter your password when you knock on it.
Knock is similar to Keycard, a Mac app I reviewed that pairs with your iPhone via Bluetooth and automatically locks it when you (and your iPhone) get out of Bluetooth range and unlocks it when you get back to your Mac. However, Knock is different in one key way – you have to prompt it intentionally, whereas Keycard relies only on the proximity of your iPhone to your Mac, which could result in unintentional locking or unlocking.
To use Knock you’ll need both a newer Mac and iOS device that have a Bluetooth 4.0 radio. For guidance on which Macs will work, check out Knock Software’s FAQ.
You can get the Knock app for your Mac for free straight from Knock Software’s site and you can get the iPhone app, which costs $3.99, from the App Store through the link below.
