Password synchronization typically increases
security by insisting on the use of strong passwords that cannot be easily guessed. Password synchronization also reduces the number of password-related requests for help, which are reported as being the single biggest demand on help desk resources. There are a number of password synchronization products available, including MTech's P-Synch, Proginet's SecurPass, and Systor's SAM Password Synchronization.
Password synchronization is among a number of identity management processes that have been developed to deal with password chaos, a too-common situation in which users have multiple identities and passwords across a variety of networks, Web sites, applications, computers and/or computing devices. According to a ZDNet article, password chaos is one of the main threats to the development of e-commerce.
