Passkeys ​

Passkeys provide WebAuthn user presence and, where available, PRF-derived holder-side material.

Role In The Model ​

Passkeys can:

  1. prove local user presence;
  2. derive or unlock holder-side material;
  3. step up expired or exhausted Wallet Session quotas;
  4. authorize sensitive operations when policy requires a cryptographic factor.

Passkeys do not make app sessions into signing authority. Passkey results are normalized into the same lane, Wallet Session/quota, capability-grant, and policy model as other auth methods.
