```JSON
{
  "detail": "Not authenticated"
}
```

### Inactive user { #inactive-user }

Now try with an inactive user, authenticate with:

User: `alice`

Password: `secret2`

And try to use the operation `GET` with the path `/users/me`.

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap { #recap }

Y para comunicarte usando WebSockets con tu backend probablemente usarías las utilidades de tu frontend.

O podrías tener una aplicación móvil nativa que se comunica con tu backend de WebSocket directamente, en código nativo.

O podrías tener alguna otra forma de comunicarte con el endpoint de WebSocket.

### Usuário inativo { #inactive-user }

Agora tente com um usuário inativo, autentique-se com:

User: `alice`

Password: `secret2`

E tente usar a operação `GET` com o caminho `/users/me`.

Você receberá um erro "Usuário inativo", como:

```JSON
{
  "detail": "Inactive user"
}
```
