Because WTForms represents an unchecked checkbox as False rather than 'unchanged', and only the 'password' 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.",
