Browser extension for KeePassXC with Native Messaging.
Based on pfn's chromeIPass. Some changes merged also from smorks' KeePassHttp-Connector.
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 or Chrome/Chromium or Microsoft Edge (requires KeePassXC 2.5.3 or newer).
Please see this document for instructions how to configure KeePassXC in order to connect the database correctly.
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 as a proxy if you prefer a non-Qt solution.
