Endpoint to obtain the required parameters for initiating the process of creating a new FIDO2 credential on the user's device during the account enrollment flow for Open Finance Brasil payment initiation. This method generates a unique challenge for each call and returns all parameters required by the W3C WebAuthn API for the credential registration process. The enrollment must be in AWAITING_ENROLLMENT status. The created FIDO2 credential will be used subsequently for strong authentication in payment operations, meeting the security requirements of the Open Finance Brasil ecosystem for Journey without Redirection (JSR).
