FingerKey app lets you unlock your Mac using iPhone’s TouchID fingerprint sensor.

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:

Little Inferno out on Mac.

Little Inferno arrived on iOS in January. It’s a wicked, little satirical adventure about burning toys that’s gotten a lot of critical acclaim. Now, the game is available on the Mac. You can pick it up directly from the developer Tomorrow Corporation, or grab it on Steam or Gamersgate.

Tomorrow Corporation says it’s also working on an iOS version that’s designed to work with older hardware, so the game will soon be playable on the iPhone 4 and fourth-gen iPod touch models as well. There’s also a Linux version in the plans. I haven’t played much of Little Inferno, but the reviews on it are really great, and it looks like a creepy, yet moving take on consumerism and “play” itself. And, of course, great games are always welcome on the Mac platform.
