KeePass (or KeePass Password Safe) is a free/open-source password manager.
KeePass 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).
KeePass is available in “Classic Edition” or in “Professional Edition”. Comparison between these two editions are fundamentally different, please refer to the Edition Comparison Table for more info.
KeePass Classic Edition runs on Windows!
KeePass Professional Edition runs on Windows, Linux and Mac OS X!
