# Simple OAuth2 con Password y Bearer

Ahora vamos a construir a partir del capítulo anterior y agregar las partes faltantes para tener un flujo de seguridad completo.

## Obtener el `username` y `password`

Vamos a usar las utilidades de seguridad de **FastAPI** para obtener el `username` y `password`.

OAuth2 especifica que cuando se utiliza el "password flow" (que estamos usando), el cliente/usuario debe enviar campos `username` y `password` como form data.
