Apparatus, systems, and methods are disclosed that operate to receiving an authentication request at a server associated with an authenticating entity from a requesting party responsive to a request being provided to the requesting party by a client terminal associated with an unauthenticated individual purporting to be an individual account owner previously authenticated with the authenticating entity. A token, from the client terminal associated with the unauthenticated individual is received, and the token includes information associated with the unauthenticated individual and a user permission authorizing the authenticating entity to share a selected portion of the information with a plurality of selected requesting parties. The server associated with the authenticating entity authenticates the unauthenticated individual as the individual account owner based on, inter alia, matching the token to a pre-registered identity uniquely associated with the individual account owner. Additional apparatus, systems, and methods are disclosed.
