Is Password Boss safe?

Low risk

Password Boss reads form field values on all web pages and forwards them to the local Password Boss desktop app via native messaging.

The extension's content script runs on every HTTP and HTTPS page, collecting form inputs including usernames, passwords, credit card numbers, and addresses, then relaying them to the background script. The background script forwards this data to the Password Boss desktop app via the native messaging host 'passwordboss.browseroverlay.chrome', or falls back to an unauthenticated localhost WebSocket at ws://127.0.0.1:52242/ if native messaging is unavailable. All data transfer stays on the local machine; no data is sent to remote servers.
