### 3.3 Use GnuTLS (for Windows) to Generate a Certificate

Но в нашем случае одно и то же приложение **FastAPI** будет работать и с API, и с аутентификацией.

Итак, рассмотрим это с упрощенной точки зрения:

* Пользователь вводит на фронтенде `username` и `password` и нажимает `Enter`.
* Фронтенд (работающий в браузере пользователя) отправляет эти `username` и `password` на конкретный URL в нашем API (объявленный с `tokenUrl="token"`).

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:

* The user types the `username` and `password` in the frontend, and hits `Enter`.
* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).

Mas, neste caso, a mesma aplicação **FastAPI** irá lidar com a API e com a autenticação.

Então, vamos rever de um ponto de vista simplificado:

* O usuário digita o `username` e o `password` no frontend e pressiona `Enter`.
* O frontend (rodando no navegador do usuário) envia esse `username` e `password` para uma URL específica na nossa API (declarada com `tokenUrl="token"`).

Pero en este caso, la misma aplicación de **FastAPI** manejará la API y la autenticación.

Así que, revisémoslo desde ese punto de vista simplificado:

* El usuario escribe el `username` y `password` en el frontend, y presiona `Enter`.
* El frontend (ejecutándose en el navegador del usuario) envía ese `username` y `password` a una URL específica en nuestra API (declarada con `tokenUrl="token"`).
