We focused a lot on security. Your password of your Mac will be saved AES 256-bit encrypted on your Mac. Your password will never leave your Mac or be sent with the Bluetooth connection.
KeyTouch is using Bluetooth 4.0 LE. Normally this would be enough to save some battery life. But by thinking again how and when Bluetooth is connecting, we developed a smarter way of connecting with Bluetooth. There is only a bluetooth connection if you scan your fingerprint. After that, the connection will be dropped automatically.
KeyTouch is saving the Mac's password on the Mac, not via any Bluetooth signal. Because of that it's not only more secure, but also fast.
