KeePass Password Safe is yet another great Portable Password Manager that can be run directly from a portable USB device. This application allows you to put all of your passwords in one database, which is then locked with a single password or master key-disk. So you only have to remember one password or insert the key-disk to unlock or gain access to the whole database. The database is encrypted as well using some of the most secure encryption algorithms AES and Twofish.
KeePass is FREE to use. Not only that, it's also open source so your able to view and even modify the inner workings if you would like.
