What happens when you click

Passkey unlock + continuity proof only. This site accepts assurance: passkey — no IDV unless you later step up to human proofs.

Customer site view

Site binding: trials-demo.lemma.id

Decision WAITING policy: passkey

Click the protected action to run the SDK.

SDK checks local site proof cache first.
Missing proof → Lemma popup derives passkey assurance (no IDV yet).
Site policy may require human proof assurance → IDV step-up, same PPID.
After first site proof, later clicks reuse the cached presentation — no action-sign popup.
Server verifies your presentation with offline revocation checks.
Business never sees passport, selfie, or cross-site ID.
