The **unauthorized** file is used to render UI when the [`unauthorized`](/docs/app/api-reference/functions/unauthorized) function is invoked during authentication. Along with allowing you to customize the UI, Next.js will return a `401` status code.

```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>
  )
}
```

### Displaying login UI to unauthenticated users

You can use [`unauthorized`](/docs/app/api-reference/functions/unauthorized) function to render the `unauthorized.js` file with a login UI.

```tsx filename="app/dashboard/page.tsx" switcher
import { verifySession } from '@/app/lib/dal'
import { unauthorized } from 'next/navigation'

export default async function DashboardPage() {
  const session = await verifySession()

  if (!session) {
    unauthorized()
  }

  return <div>Dashboard</div>
}
```

```jsx filename="app/dashboard/page.js" switcher
import { verifySession } from '@/app/lib/dal'
import { unauthorized } from 'next/navigation'

export default async function DashboardPage() {
  const session = await verifySession()

  if (!session) {
    unauthorized()
  }

  return <div>Dashboard</div>
}
```

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

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