No próximo capítulo, você verá uma implementação realmente segura, com hash de senha e tokens <abbr title="JSON Web Tokens">JWT</abbr>.

Mas, por enquanto, vamos nos concentrar nos detalhes específicos de que precisamos.

For this to work, you need to `pip install python-dotenv`.

### The `.env` file

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Read settings from `.env`

And then update your `config.py` with:
