What is a passkey on amazon? It’s Amazon’s passwordless sign-in option that lets you log in using the same action you use to unlock your device—Face ID, a fingerprint, or a lock-screen PIN—instead of typing a password. Amazon describes passkeys as easier to use and less susceptible to phishing than passwords or one-time codes sent by text message, and they’re available across browsers, the Amazon Shopping app (iOS and Android), and Audible.
