Nowadays, there’s an ongoing tech-trend to implement the lock-and-key design in personal digital accounts. For example, Google lets users log in to their accounts by plugging in a USB drive (USB Security Key). Now, most Mac users often also use an iOS device, and Apple Watch has also been released. So wouldn’t it be nice if you could remotely lock and unlock your Mac using your iOS device or Apple Watch? Today, we have come up with a few solutions that let you do just that.

These solutions take away the need for providing a password every time you want to unlock your Mac. Once the Mac has been paired up with your iPhone, iPad, iPod Touch, or Apple Watch, you can remotely unlock it (from a limited distance) using your Touch ID, iOS Passcode, or directly using your iOS device or even Apple Watch. This can be a handy feature to use when you’re in a hurry, or if you want to unlock your computer in front of someone else, without risking a possible password theft.

The password is stored and exchanged between devices using 256-bit AES encryption. You’ll also need to pair your iOS device with your Mac via Bluetooth during the setup process.

Once the setup process is complete, you’ll be able to lock and unlock your computer remotely using your Touch ID supported iPhone or iPad. The app supports unlocking multiple computers using a single Touch ID. FingerKey also has a Today Widget for faster access to the app from the iOS Notification Center.
