KeePass/MacPass Helper extension adds an action button to your browser toolbar area. Pressing the button opens a panel that displays all the matching credentials for the current domain. You can either insert the username, password, or even both through the action buttons. The extension also can submit the form if you would like to. This extension offers a built-in OTP (One-time password) tool so you don't need to have a separate extension for that. The OTP credential can optionally be saved in SHA-256 encryption to make sure your OTP secrets are safe.

This extension supports the following applications:
1. KeePass application with KeePassHttp installed
2. KeePassXC with a custom manifest (uses native messaging to communicate)
3. Direct read of KDBX3 or KDBX4 databases (when you cannot install a native application)
4. Any other alternatives that support HTTP communication (such as MacPass)

Notes:
1. When using this extension, first make sure the login or password input box is selected on the page before opening the panel. Insertion occurs only if an input element is selected on a form.
2. It is possible to generate one-time password tokens using this extension.
3. This extension optionally supports automatic logins.
4. Native messaging that is supported by KeePassXC is now covered. Go to the options page to configure the extension to work with KeePassXC.
