A technique for accessing an electronic commerce service is provided in which information associated with a subscriber's account with an electronic commerce service is stored along with first subscriber credentials for that subscriber to access the services. An account is created during enrollment. The enrollment is associated with a first electronic commerce participant, i.e., a biller or a payee. A request for the subscriber to access an electronic commerce service in association with a second electronic commerce participant is received. Without the subscriber, or any other entity providing the credentials, the subscriber is granted access to the requested service utilizing the account established in association with the first participant. This access is granted based upon the subscriber providing information other than credentials, the provided information being information stored by the service provider in association with the enrollment.
