KeePass is a password manager which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish).
To install automatically KeePass Professional Edition on your LiberKey, make sure you previously activated files associations from the "LiberKey Tools" menu.
You can then open the file directly to start the installation.
