File created by KeePass Password Safe, a free password manager for Windows; stores an encrypted database of passwords that can only be viewed using a master password set by the user; used to securely store personal login credentials for Windows, email accounts, FTP sites, e-commerce sites, and other purposes.
The KDBX format was introduced with version 2 of KeePass. The previous version used the .KDB format. KeePass 2 can import older KDB files as well as export to the KDB format.
