Touch ID with Mac and iPhone - Lock Screen

It would be awesome if you could use your iPhone to login into things on your Mac. This highlights a potential interaction on the lock screen.

Examples of usages: Safari, Mac App Store, iTunes, Account Login, etc.

- Would work well with iCloud Keychain (one way to match when device should be prompted)

- Handles like a Passbook notification (simply lights up the screen, disappears after successful login - from device or the Mac, when cancelled, or after inactivity)

-Bluetooth connection not only connects the two devices but calculates distance to eliminate prompts when the device is "out of arms reach."

If the Mac got Touch ID directly integrated, that would be the ultimate (and most optimal) solution. However, opportunities for expansion:

- AppleTV

- Car (with CarPlay, unlock your car while in range)
