SAINTlogin allows users to log-in to a website or to a private network by dialing a number on their cell phones rather than by using passwords and user-IDs. The call is free since the system hangs up after the first ring. If the caller is recognized, a private session is established, and access to the requested pages is granted. The SAINTlogin API enables developers to integrate SAINTlogin with their websites. Doing so requires the use of SOAP calls issued in XML format.
