Payment Passkey
Payment Passkey
Payment Passkey
is an e-commerce authentication solution that is
built on Fast Identity Online (FIDO). Payment Passkey
uses device-based
authentication to provide a consistent and secure payment experience. Payment Passkey
provides a streamlined customer experience and enhances security
by standardizing local authentication. Payment Passkey
also offers
eligibility for liability shift under the digital authentication framework.A
Payment Passkey
credential is assigned to a device and card
combination after a successful cardholder authentication. You can use this Payment Passkey
credential during cardholder checkout when the same device and
payment card are used. This avoids repeated calls to the issuer and optimizes the
cardholder's payment experience. IMPORTANT
This feature is in the pilot phase. You have early access
to this feature even though it might contain bugs or unfinished work. You should
consider the risk when using this feature.
Payment Passkey Workflow
Payment Passkey
WorkflowThis workflow illustrates the process of integrating to Passkey
Service and binding a network token to a device or browser. There are three possible
outcomes when you send a request to determine if FIDO authentication is available
for a network token:
- AUTHENTICATE: The device and network token combination is already registered withPayment Passkeyand enrollment and step-up are not required. The cardholder can authenticate immediately using their passkey. See Authenticate with Passkey.
- AUTHENTICATION_REGISTRATION: NoPayment Passkeyexists yet for the device and tokenized card combination and the device and token are eligible to be registered withPayment Passkey. You must register a passkey before authentication can take place. See Register a Passkey and Authenticate.
- STEP_UP_AUTHENTICATION: The device and tokenized card is not yet registered withPayment Passkeyand the issuer has challenged the device binding. You must complete an issuer‑required step‑up authentication before the device can be approved and passkey registration can proceed. See Step-up Authentication for Registration.
