Systems and methods for facilitating access to stored information associated with a user, where a service provider receives, from a network entity controlling access to the stored information, a first message component encrypted with a first crypto-key associated with the network entity that can be decrypted by the network entity and a network address associated with the stored information. The service provider then receives a request for information enabling access to the stored information from an access portal associated with the user. Next, the service provider generates a response that includes the network address and the first message component and transmits the response to the access portal. The generated response is extensible by the access portal to include a second message component. The second message component is encrypted with a second crypto-key associated with the access portal. The extended response is usable to obtain access to the stored information.
