KeePass Password Manager (or Password Safe) is a popular open-source password manager with support for several operating systems, one being Microsoft Windows. The developer also supports various distros of Linux, mobile devices and Mac OS X!
The big advantage of KeePass over many other password managers is its very unique ability to shield the master key dialogue from keyloggers as it works on a secure desktop.
Like many password managers, whether freeware or commercial, this one saves a list of passwords behind very tight encryption and thus passwords can only be unlocked by providing the master key.
Version 2.54 is a freeware program which does not have restrictions and it's free so it doesn't cost anything.
Virus and Malware Tests: The program has been tested with several antivirus applications and has tested clean of viruses, malware or trojans.
