KeePassXC

KeePassXC is a free and open-source password manager. It started as a community fork of KeePassX (itself a cross-platform port of KeePass).

It is built using Qt5 libraries, making it a multi-platform application which can be run on Linux, Windows, macOS, and BSD.

KeePassXC uses the KeePass 2.x (.kdbx) password database format natively. It can also import (and convert) version 2 and the older KeePass 1 (.kdb) databases. KeePassXC supports having key files and YubiKey challenge-response for additional security.

The Electronic Frontier Foundation mention KeePassXC as "an example of a password manager that is open-source and free". A security review of KeePassXC version 2.7.4 was completed in late 2022.

An accompanying browser extension is available for Firefox, Tor-Browser, Google Chrome, Vivaldi, Microsoft Edge, and Chromium. Extensions can be linked by enabling browser integration in the desktop application.
