KeePass is a free, open source program that stores your passwords securely using two different encryption algorithms: AES and Twofish. It is customizable and has many thoughtful features like automatically clearing the clipboard after pasting your username or password. There are also many plugins you can get to extend the functionality of KeePass. KeePass allows you to set expiration dates on passwords, generate random strong passwords, organize passwords into groups, as well as keep notes and website links stored under each password. KeePass runs on Windows, Linux, Mac OS X, the iPhone and Android phones. You can use Dropbox to synchronize your passwords between different computers.
