In this paper the authors describe a service that allows users one-time password access to any web account, without any change to the server, without changing anything on the client, and without storing user credentials in-the-cloud. The user pre-encrypts his password using an assigned set of keys and these encryptions are sent as one-time passwords to his cell phone or carried. To login he merely enters one of the encryptions as prompted, and the URRSA service decrypts before forwarding to the login server. Since credentials are not stored (The service merely decrypts and forwards) it has no need to authenticate users.
