Te da toda la flexibilidad para elegir aquellas que se ajusten mejor a tu proyecto.

Y puedes usar directamente muchos paquetes bien mantenidos y ampliamente usados como `passlib` y `PyJWT`, porque **FastAPI** no requiere mecanismos complejos para integrar paquetes externos.

Pero te proporciona las herramientas para simplificar el proceso tanto como sea posible sin comprometer la flexibilidad, la robustez o la seguridad.

E você pode usar diretamente muitos pacotes bem mantidos e amplamente utilizados, como `passlib` e `PyJWT`, porque o **FastAPI** não exige mecanismos complexos para integrar pacotes externos.

Mas ele fornece as ferramentas para simplificar o processo o máximo possível, sem comprometer a flexibilidade, robustez ou segurança.
