Self-service functionality can assist with password resets, recoveries and account unlocks. By using multiple security questions and answers functionality PortalGuard is able to perform all resets directly from the end-user's machine if desired. This also includes Offline Mode, which allows the forgotten password to be shown to roaming users in clear text when they are offline, so as to continue work without returning to the office.
