With iPhone 5S, Apple has introduced a new security feature on its smartphone, TouchID which was later made available on iPad and iPad Mini too. This feature lets you unlock your iPhone using your fingerprint, which means non authorized user wont be able to get sneak peak on your device. Later this feature was expanded and now you can use it to pay bill via Apple Pay.
But now using a app, FingerKey you can unlock your Mac using TouchID sensors from your iPhone, this app utilizes third-party access to Touch ID APIs and can work with iPhone 5S, iPhone 6 and iPhone 6 Plus, however there is no word whether it can work with iPad Air 2 or iPad Mini 3.
After the launch of iOS 8 and OS X Yosemite, we had seen that Apple has integrated iOS device and Mac, like you can read messages on Mac, accept calls and so on, so it may be possible Apple could launch this feature in upcoming iOS. Here this app utilizes Bluetooth 4.0 LE (low energy) and 256-bit AES encryption to establish a secure between your iPhone and Mac, it also comes with a widget which you can place on your notifications center so that you can access it anytime easily.
Developer has said that they are working on a similar app which can soon unlock Windows and Linux and soon you will be able to unlock devices using dots or patterns instead of just TouchID, which means soon this app can be compatible with older iPhone’s which do not have TouchID.
