Per-action approval

Every payment is signed by the user's passkey — not a stored token. Replay-proof and non-repudiable.

What you sign is what you see

Amount, recipient, and currency are bound into the signature, so they can't be altered after approval.

Instant receipts

Paswad emails a signed receipt the moment a transaction is approved — your real-time tripwire.
