A new app called FingerKey allows Mac users to unlock their computer using Apple’s Touch ID fingerprint sensor on the iPhone 5s, 6, or 6 Plus.
That means you’ll be able to login to your Mac using your iPhone’s fingerprint sensor rather than typing in a password each time. The app takes advantage of Apple opening up the Touch ID sensor to third-party apps for logins after previously being reserved for unlocking the device itself and authenticating App Store and iTunes purchases.
The FingerKey app includes the ability to unlock multiple computers from a distance, 256-bit AES encryption, and a Notification Center Today widget for quick access.
The developer says that support for logging into Windows and Linux computers is coming soon as is a Pattern Unlock feature for logging in via touchscreen gestures.
We recently wrote about a similar app, which also used a Bluetooth connection, that allowed users to unlock their Mac using by knocking on their iPhone’s screen.
FingerKey is available on the App Store for $1.99 and the developer shared the video below of the app in action:
