This document summarizes the problems users experience when managing too many passwords. It describes the various approaches available to organizations to reduce the password burden on users and to
improve the security of their authentication systems.
Given this background information, this document goes on to describe the basic architecture of traditional
enterprise single sign-on (E-SSO) systems. It describes their strengths, along with their security, usability and cost issues.
Finally, a new approach is presented, to deliver most of the same advantages of a traditional E-SSO system but without any of the traditional issues. The new approach replaces a database of stored passwords with
a password synchronization process. This is the approach embedded in Hitachi ID Login Manager.
