Re-authentication

Confirm that a returning customer is the same person, with only a selfie. Send "type": "reauth" and your vendor_data for the customer; the selfie, with liveness, is matched against the face of their last approved verification: the chip portrait if it was read, else their approved selfie, else the document portrait. It is charged like the liveness and face match steps.

  -d '{"type":"reauth","vendor_data":"customer-1042"}'

The answer adds reference (the verification whose face is used and its source: stored_chip, stored_selfie or stored_document). The signed result carries the same as reauth_of. Stored faces are deleted on your biometric retention period (Settings → Organization); when there is none left, the answer is 409 with code no_reference, and the customer needs a full verification. Earlier re-authentications are never used as the reference.
