HTTP Headers WordPress Plugin – Referrer-Policy

The HTTP Headers plugin can set a referrer-policy header to control what information is sent through the referer header with URI requests. This prevents URLs with sensitive information from showing up in web analytics software logs. For example, clicking links on a password reset page could send user credentials within the referrer.
