```Python hl_lines="89-106"

## Update the `/token` *path operation*

Create a `timedelta` with the expiration time of the token.

Create a real JWT access token and return it.

!!! tip
    We are using an invented header to simplify this example.

    But in real cases you will get better results using the integrated [Security utilities](security/index.md){.internal-link target=_blank}.

## Another module with `APIRouter`

Ainda assim, a última experiência não foi a melhor.

Essa poderia ser a história paralela equivalente aos hambúrgueres.

Para um exemplo "mais real", imagine um banco.

Até recentemente, a maioria dos bancos tinha muitos caixas e uma grande fila.

Todos os caixas fazendo todo o trabalho, um cliente após o outro.

For this simple example, we are going to just be completely insecure and return the same `username` as the token.

!!! tip
    In the next chapter, you will see a real secure implementation, with password hashing and <abbr title="JSON Web Tokens">JWT</abbr> tokens.

    But for now, let's focus on the specific details we need.

=== "Python 3.10+"

    ```Python hl_lines="87"

But still, the final experience is not the best. 😞

This would be the parallel equivalent story for burgers. 🍔

For a more "real life" example of this, imagine a bank.

Up to recently, most of the banks had multiple cashiers 👨‍💼👨‍💼👨‍💼👨‍💼 and a big line 🕙🕙🕙🕙🕙🕙🕙🕙.

    And then pass the `hashed_password` argument with the value to save.

!!! warning
    This example is not secure, the password is not hashed.

    In a real life application you would need to hash the password and never save them in plaintext.

    For more details, go back to the Security section in the tutorial.

Luego, cuando llega tu turno, haces un trabajo "productivo" real 🤓, procesas el menú, decides lo que quieres, lo que quiere esa persona 😍, pagas 💸, verificas que das el billete o tarjeta correctos, verificas que te cobren correctamente, que el pedido tiene los artículos correctos, etc.
