KeePass is a very useful tool for anyone with several website accounts with different passwords. KeePass stores your usernames and passwords for websites, documents, or whatever you may have a password for. It also has a random password generator built in which I use to generate all of my passwords. KeePass encrypts your data to prevent hacking by using a random set of typed keys and a passover of your mouse over a random image. This ensures that the method of encryption is unique to your password database which is a feature I consider to be important. You can then set the opening of the database to a set password, a key file that has to be loaded to open the database, or both.
One feature that I consider to be very useful is how it handles the copying of passwords from the database. The password is copied to the clipboard only for a limited time. After that time has passed, the password is cleared from the clipboard and memory, thusly preventing another user on your computer from getting your passwords from the clipboard. The database will also automatically lock after a certain period of time.
The only problem I have with KeePass is that you can't integrate it with your browser to load passwords when you visit a website. Instead, you have to open the program separately to get your passwords. KeePass also supports the capability to add plugins which can add this feature, however, the plugins are not supported by KeePass and could potentially be used to infiltrate your security.
