# KeePassXC-Browser

Browser extension for [KeePassXC](https://keepassxc.org/) with [native messaging](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Native_messaging).

## Download and use

This browser extension was first supported in KeePassXC 2.3.0 (release end of 2017). In general it is advised to only use the latest available release.

Get the extension for [Firefox](https://addons.mozilla.org/en-US/firefox/addon/keepassxc-browser/) or [Chrome/Chromium](https://chromewebstore.google.com/detail/keepassxc-browser/oboonakemofpalcgghocfoadofidjkkk) or [Microsoft Edge](https://microsoftedge.microsoft.com/addons/detail/pdffhmdngciaglkoonimfcmckehcpafo).

Please see this [document](https://keepassxc.org/docs/KeePassXC_GettingStarted.html#_browser_integration) for instructions how to configure KeePassXC in order to connect the database correctly.

## How it works

KeePassXC-Browser communicates with KeePassXC through _keepassxc-proxy_. The proxy handles listening to STDIN/STDOUT
and transfers these messages through Unix domain sockets / named pipes to KeePassXC. This means KeePassXC can be used and started normally without inteference from
Native Messaging API. KeePassXC-Browser starts only the proxy application and there's no risk of shutting down KeePassXC or losing any unsaved changes. You don't need to install keepassxc-proxy separately. It is included in the KeePassXC application package. Alternatively you can use
[keepassxc-proxy-rust](https://github.com/varjolintu/keepassxc-proxy-rust) as a proxy if you prefer a non-Qt solution.
