What is KeePass?
Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your homepage's ftp password, online passwords (like CodeProject member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, homepage, etc. Unimaginable.

KeePass is a free/open-source password manager or safe 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-disk. So you only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). For more information, see the features page.

Is it really free?
Yes, KeePass is really free, and more than that: it is open-source (OSI certified). You can have a look at its full source and for example check if the encryption algorithms are implemented correctly.

Perhaps you wonder why I decided to make it open-source. The answer is relatively simple: in my opinion all software that has something to do with security should be open-source. Here's a quote of Bruce Schneier that sums it up pretty good:

As a cryptography and computer security expert, I have never understood the current fuss about the open source software movement. In the cryptography world, we consider open source necessary for good security; we have for decades. Public security is always more secure than proprietary security. It's true for cryptographic algorithms, security protocols, and security source code. For us, open source isn't just a business model; it's smart engineering practice.

KeePass Features
* KeePass supports the Advanced Encryption Standard (AES) and the Twofish algorithms to encrypt its password databases.
* your passwords are encrypted while KeePass is running, so even if Windows caches the KeePass process to disk, this wouldn't reveal your passwords anyway.
* One master password decrypts the complete
* KeePass runs, without downloading any additional libraries, on Windows 95, 98, 98SE, ME, NT, 2000, XP (Home & Pro, 32-bit & 64-bit), 2003 and Vista.
* The password list can be exported to various formats like TXT, HTML, XML and CSV.
* KeePass supports time fields: creation time, last modification time, last access time and expiration time.
