First introduced with the iPhone 5s, Apple’s Touch ID fingerprint sensor is one of the easiest and most convenient ways to unlock your iPhone and iPad. And now, thanks to a new app, it’s also one of the easiest and most convenient ways to unlock your Mac.
Called FingerKey, this new utility works by using Bluetooth 4.0 (what else?) to pair with your Mac, then forms a low latency, low energy wireless connection with an extra layer of 256-bit AES encryption on top to keep things secure.
Once you’ve got things paired, unlocking your Mac is as simple as getting into Bluetooth range, opening up the app, and putting your finger against the home button. There’s also a Notification Center Widget that makes things even easier, and FingerKey can actually unlock multiple Macs at a time.
Unfortunately, there’s a caveat. Right now, there appears to be an issue with the iPhone 6 and iPhone 6 Plus that prevents the app from properly working under some circumstances. The developers say, though, that an update is on its way that will fix the issues for good.
You can download FingerKey from the iOS App Store for just $1.99.
