Password Safe is a free open-source program for storing passwords in the Windows operating system.

After filling in the master password the user has access to all account data entered and saved previously. The data can be organized by categories, can be sorted and searched. The key combination Ctrl+C copies the password of a selected account into the clipboard, Ctrl+U copies user ID. The program can be set to minimize automatically after a period of idle time and clears the clipboard. It is possible to compare and synchronize two different password databases.

The program was initiated by Bruce Schneier and is now developed by a group of volunteers at SourceForge.
