Y todas estas miles de *path operations* pueden ser tan pequeñas como 3 líneas:

## Resumen

Ahora puedes obtener el usuario actual directamente en tu *path operation function*.

Ya estamos a mitad de camino.

Solo necesitamos agregar una *path operation* para que el usuario/cliente envíe realmente el `username` y `password`.
