Single sign-on for access to a central data repository

Abstract

Systems and methods for providing access to an information account stored in a central data repository. The information account is associated with a consumer and is subject to the consumer's control and management. Consumer authentication information is input by the consumer in connection with a first request for access to the information account via a first web-site. Responsive to authentication of the consumer, a single sign-on feature may be activated for automatically managing subsequent authentications of the consumer so that the consumer will not be required to again input the consumer authentication information upon initiating a second request for access to the information account while interacting with a subsequent web-site that is configured to provide access to the information account upon authentication of the consumer. The single sign-on function may be deactivated upon the occurrence of a terminating event, such as the expiration of a time-out interval.
