Perspective
Auth21 Perspective
Login proves identity. Who proves intent for this action?
OAuth answers who the user is. Step-up at login still does not answer whether they authorized this transfer, this deletion, or this device bind right now.
Most platforms still treat security as a one-time event at session start. In practice, sensitive actions need a separate layer: reusable, auditable verification tied to the operation context — not just the login form.
Auth21 Perspective
A signing device ≠ a logged-in user
Cryptographic possession is a different layer from identity. Conflating the two creates a false sense of security for critical operations.
Possession protocols — like POAP — exist to answer: which device is operating now, with a registered key, after identity is already established. That complements OAuth; it does not replace it.
