receiving an authentication prompt that excludes sensitive consumer information from enrollment information previously provided by the consumer to the authentication system; and

communicating the authentication prompt that excludes sensitive consumer information to the merchant, wherein communicating the authentication prompt that excludes sensitive consumer information to the merchant includes displaying an issuer-branded window to the merchant that prompts for authentication information and excludes the sensitive consumer information.

communicating enrollment confirmation information to the merchant based on whether the financial account identifier is enrolled.

12. The method of claim 11 , wherein the transaction type information indicative of a type of transaction engaged in between a consumer and the merchant is communicated to the authentication system with the enrollment confirmation request.

13. The method of claim 11 , wherein the response indicative of whether the financial account identifier is enrolled is tailored based on the type of transaction engaged in between the consumer and the merchant.
