Touch ID
A fingerprint recognition feature available on some Mac computers. With Touch ID, you can unlock your Mac and some password-protected items, use Apple Pay to make purchases on the web, and purchase items from the iTunes Store, App Store, and iBooks Store.
Touch ID is located at the top-right corner of the keyboard, next to the Touch Bar or row of function keys, depending on the model of your Mac.
