Because WTForms represents an unchecked checkbox as False rather than \u0027unchanged\u0027, and only the \u0027password\u0027 field is special-cased against this problem, a POST to /settings that omits the api_access_token_enabled field (e.g. a minimal scripted request) silently disables API key enforcement for the entire REST API, exposing the full watch list, history, and configuration to unauthenticated requests."
