+The `<Authenticated>` component calls [the `useAuthState()` hook](./useAuthState.md), and by default optimistically renders its child component - unless the authentication check fails. Use it as an alternative to the `useAuthenticated()` hook when you can't use a hook, or you want to support pessimistic mode by setting `requireAuth` prop, e.g. inside a `<Route element>` commponent:
