Is Password Manager safe?

Low risk

Password Manager lets a URL parameter trigger autofill of a referenced saved login into the current page.

On HTTPS pages, the extension reads an fskeyLoginId value from the page URL and asks its background script for that saved entry. The background script retrieves the matching username and password from the local fskey native app and sends them back to be filled into the active page's login fields.
