Quickly lock MacOS with the TouchID button

If you press the TouchID button with your main finger, it does nothing, but did you know that if you press the TouchID button with a finger that MacOS does not have a fingerprint record for, your screen will immediately lock?

This is much quick than using hot corner — which, let’s be honest — gets triggered accidentally more often than not.

It’s also one less shortcut key-combo you’ll need to remember going forward.

This works with both laptop and external keyboard TouchID buttons.
