The **unauthorized** file renders UI when the [`unauthorized`](/docs/app/api-reference/functions/unauthorized) function is invoked.

Before streaming starts, Next.js returns a `401` status code. After streaming starts, the status code remains `200` and the unauthorized UI renders in the response. Next.js injects a `<meta name="robots" content="noindex" />` tag in both cases. See [Status codes](/docs/app/api-reference/file-conventions/loading#status-codes) for details.

```tsx filename="app/unauthorized.tsx" switcher
import Login from '@/app/components/Login'

export default function Unauthorized() {
  return (
    <main>
      <h1>401 - Unauthorized</h1>
      <p>Please log in to access this page.</p>
      <Login />
    </main>
  )
}
```

```jsx filename="app/unauthorized.js" switcher
import Login from '@/app/components/Login'

export default function Unauthorized() {
  return (
    <main>
      <h1>401 - Unauthorized</h1>
      <p>Please log in to access this page.</p>
      <Login />
    </main>
  )
}
```
