Re-identification methods available for this MPxN. Empty when exists is false. Possible values: passkey-assert (credentials registered), magic-link (email stored), passkey-register (always present — a new passkey can always be enrolled).

The re-identification method to use.

magic-link — single-step. The register dispatches a signed link to the stored email address. Optionally supply redirect-url to send the customer back to the Data User's app after clicking; otherwise the customer lands on central.consent. Poll or check GET /identity-records/{ir}/re-identify/{token-ref} to confirm.

passkey-assert — two-step redirect. The response contains a passkey-redirect with a short-lived URL to id.central.consent. Redirect the customer there; the register runs the WebAuthn assertion against the stored public key on its own origin, then redirects back with ?dar-passkey-token={token-ref}. Call GET /identity-records/{ir}/re-identify/{token-ref} once to confirm.

passkey-register — two-step redirect for new device enrolment. Same flow as passkey-assert but runs a registration ceremony instead of assertion. Stores a new public key credential on the Identity Record and confirms re-identification on success.

Available options:
magic-link,
passkey-assert,
passkey-register
