KeePass for U3
KeePass is a free, open source password manager. With the Internet being such a prevalent force in today's tech-savvy world, you're bound to have many accounts at many different websites all around the web. Security experts and common sense both dictate that you should use strong, secure, and unique passwords for each site. If your passwords are unique but too short, they will be easy to figure out. If you use a complex password, but use it on every site with which you have an account, it's only a matter of time before one account will be compromised, then they will all fall one by one
That's why you need KeePass. Rather than having to remember tens or even hundreds of long, complicated passwords, KeePass does all the work for you. It automatically generates good quality passwords for all the sites you visit, and stores them in its high-security database. Its databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). They can only be unlocked with a master password and/or key file. In short, KeePass incorporates all the good features of strong password security and none of the drawbacks.
Also, KeePass is very convenient. It can be integrated with Firefox and Google Chrome for automatic and secure transmission of your account data to login forms. You can set it to minimize upon login, and also when you copy a password to the clipboard. You can have it automatically lock itself when it hasn't been used in a while. With all these features, KeePass is easy to recommend.
