Nunca almacenes contraseñas de usuarios en texto plano. Siempre almacena un "hash seguro" que puedas verificar luego.

Si no lo sabes, aprenderás qué es un "hash de contraseña" en los [capítulos de seguridad](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.

## Múltiples modelos

Aquí tienes una idea general de cómo podrían ser los modelos con sus campos de contraseña y los lugares donde se utilizan:

Vemos que vamos a necesitar algunas dependencias usadas en varios lugares de la aplicación.

Así que las ponemos en su propio módulo `dependencies` (`app/dependencies.py`).

Ahora utilizaremos una dependencia simple para leer un encabezado `X-Token` personalizado:
