Most of Microsoft Windows operating systems give an opportunity for user to change domain password from his/her workstation, but only in case the workstation is a member of this domain. If the workstation can't join a domain (in particular, in case it is Windows XP Startseite Edition workstation), if there are multiple domains, or in peer-to-peer network the user is forced to ask network administrator to change network passwords. SynchroPass can solve this problem. It allows to synchronously change passwords for current user account on local computer, in one or several domains, and on one or multiple peer-to-peer servers. The program also can inform user about passwords expiration and invalidity. Using SynchroPass, it is possible to build secure peer-to-peer network. SynchroPass can be used on systems with Microsoft Windows NT 4.0, Windows 2000, Windows XP, Windows 2003 Server or later operating system installed. SynchroPass can not be used on Windows 9X computers. Also it can't change passwords for shared network resources on Windows 9X servers. SynchroPass doesn't require administrative privileges to run. SynchroPass supports multiple languages. Currently installation package includes support for English and Russian. Support for additional languages may be added in future in form of add-in packages.
