Create an Instrument Identifier Token {#concept}
================================================

Before you can set up and authenticate a customer using the Passkey Service, you must create an instrument identifier token to contain the customer's payment credentials.  
Instrument identifier tokens represent tokenized payment account numbers. Tokenized payment account information includes a primary account number (PAN) for card payments, or a US or Canadian bank account number and routing number for an ACH bank account. An instrument identifier token can exist independently, or it can be associated with a payment instrument.
