UNIX User Password Modifier (2UPM) is a Windows application which is designed for batch modifying, generating and managing the user passwords on the various UNIX/Linux hosts. It may be useful for the UNIX/Linux system administrators, programmers and normal users, specially, if you manage or use many UNIX/Linux hosts, you will find it to be very useful due to the following benefits:

* Save your valuable time, for instance: changing back a password to extend its operating period and reuse it before it expires, you must enter 10 commands/strings: login - password - passwd - old - new - new - passwd - new - old - old, it will take you a minute nearly if fast and correctly, changing 100 passwords will take 100 minutes. 2UPM does this in only a few seconds.
* Avoid entering the incorrect passwords and forgetting them.
* To free yourself from the troublesome passwords generating and management.

Generally, the source of the passwords modifying requirements are security ensuring for the OS and/or applications, internal request (company or department even yourself) and external request (for instance: Sarbanes Oxley (SOX) law). If your OS and/or applications have these requirements, 2UPM can increase your work efficiency many times in this domain.
