A passkey is a credential that allows for a user to authenticate successfully without ever using a password.

What is a passkey?

Passkeys are saved in a device and server-side creating a cryptographic key pair.  Passkeys provide the ability for a user to automatically access their FIDO credential on many of their devices — including new ones — without having to re-prove identity and re-enroll on each device.
