As promised in a previous post, I am now going to further detail KeePass and give some arguments on why I like using it. For more information please refer to the KeePass website.
So, what is KeePass? KeePass is an open source password manager. This means it's a free application used to store user credentials. However, once you begin using it, you will find it can do much more than just store passwords. The nice thing about KeePass is that you can find a build/implementation for just about any OS out there. The different implementations are available for download here. Note that there is also a portable version if you don't have access rights to install the application, or if you wish to keep the entire application on an USB stick.
