Identity and access management (IAM)

Passwordless / passkey

A login in which identity is proven with a cryptographic key stored on the device and unlocked by biometrics or a PIN, instead of remembering a secret. A passkey is a FIDO2 credential that eliminates passwords, so there is nothing to steal via phishing or a password database leak.
