Apple White Paper: ‘Face ID Security’ (PDF)

New from Apple, a white paper describing the security aspects of Face ID. Here’s a bit on how you’ll confirm payments:

To authorize an in-store payment with Face ID, you must first confirm intent to pay by double-clicking the side button. You then authenticate using Face ID before placing your iPhone X near the contactless payment reader. If you’d like to select a different Apple Pay payment method after Face ID authentication, you’ll need to reauthenticate, but you won’t have to double-click the side button again.

To make a payment within apps and on the web, you confirm intent to pay by double-clicking the side button, then authenticate using Face ID to authorize the payment. If your Apple Pay transaction is not completed within 30 seconds of double-clicking the side button, you’ll have to reconfirm intent to pay by double-clicking again.

Apple also published a support document with a summary of this stuff, and Rene Ritchie has a good deep dive at iMore.
