Register a Passkey and Authenticate

When you request authentication options for a tokenized card, the response indicates which
Payment Passkey
sequence to take for the current device and token combination:
  • AUTHENTICATE
  • AUTHENTICATION_REGISTRATION
  • STEP_UP_AUTHENTICATION
This section describes what to do when the
action
field in your request to the
/tms/v2/tokenized-cards/
{tokenId}
/authentication-options
endpoint returns a value of
AUTHENTICATION_REGISTRATION
. When the response returns
AUTHENTICATION_REGISTRATION
, no passkey exists yet but the device has been approved and the user must complete a one‑time passkey registration. For information about the
Payment Passkey
flow, see Payment Passkey.
