* El frontend (ejecutándose en el navegador del usuario) envía ese `username` y `password` a una URL específica en nuestra API (declarada con `tokenUrl="token"`).
* La API verifica ese `username` y `password`, y responde con un "token" (no hemos implementado nada de esto aún).
    * Un "token" es solo un string con algún contenido que podemos usar luego para verificar a este usuario.
