KeePassXC Browser Integration

If you use KeePassXC Browser with Misubi Browser on macOS, place the Native Messaging manifest in the Misubi-specific directory.

Manifest location on macOS

Use this exact path:

~/Library/Application Support/Misubi/NativeMessagingHosts/org.keepassxc.keepassxc_browser.json

Manifest example

Create the file with this content:

{
"allowed_origins": [
  "chrome-extension://pdffhmdngciaglkoonimfcmckehcpafo/",
  "chrome-extension://oboonakemofpalcgghocfoadofidjkkk/"
],
"description": "KeePassXC integration with native messaging support",
"name": "org.keepassxc.keepassxc_browser",
"path": "/Applications/KeePassXC.app/Contents/MacOS/keepassxc-proxy",
"type": "stdio"
}

Important checks

• The file name must match the host name exactly: org.keepassxc.keepassxc_browser.json.
• The path value must point to a valid keepassxc-proxy binary on the machine.
• Misubi Browser can still discover fallback manifests from Chromium, Google Chrome, or Brave, which can make troubleshooting confusing if multiple manifests exist.

Recommendation

For Misubi Browser installs, use the Misubi-specific path as the canonical location and avoid relying on fallback manifests from other browsers during debugging.
