Is KeyGuard - Password Manager safe?

Low risk

KeyGuard - Password Manager lets approved sites and any localhost page read its login token and derived stashword.

Its manifest allows pages on app.key-guard.io and localhost to connect to the extension. When they send the extensionPresent message, the service worker returns whether the extension is present along with the stored credentials token and derived stashword.
