Note about KeePassHTTP

KeePassHTTP is not a highly secure protocol and has certain flaw which allow an attacker to decrypt your passwords when they manage to intercept communication between a KeePassHTTP server and PassIFox/chromeIPass over a network connection (see here and here). KeePassXC therefore strictly limits communication between itself and the browser plugin to your local computer. As long as your computer is not compromised, your passwords are fairly safe that way, but use it at your own risk!

Installation

Pre-compiled binaries can be found on the downloads page. Additionally, individual Linux distributions may ship their own versions, so please check out your distribution's package list to see if KeePassXC is available.
