# HTTP Basic Auth

Para los casos más simples, puedes usar HTTP Basic Auth.

En HTTP Basic Auth, la aplicación espera un header que contiene un nombre de usuario y una contraseña.

Si no lo recibe, devuelve un error HTTP 401 "Unauthorized".

Y devuelve un header `WWW-Authenticate` con un valor de `Basic`, y un parámetro `realm` opcional.

Eso le dice al navegador que muestre el prompt integrado para un nombre de usuario y contraseña.
