Token is the one place where all of your physical and digital keys live : credit cards, house keys, transit cards, car keys, or your access badge . These are credentials you use to prove who you are. We built a secure environment for these artifacts to live on from a combination of asymmetric cryptography, biometrics, and a secure element. We’ve used ingrained behavior (swiping a card, entering a password, using house keys) as our benchmark for convenience . We didn’t build a feature unless we could make it faster and easier.
