Abstract: A system and method for tokenless authentication. A customer can enroll with a customer identifier and by providing biometric samples. A customer checking, credit or debit account can be associated with the information provided by the customer. When the customer seeks to enter into a transaction, the customer provides his identifier and biometric information. The identifier can be used to locate the biometric information stored for the customer during enrollment. If the received biometric matches the stored biometric, the customer can be authenticated and the transaction approved.
