`secrets.compare_digest()` necesita tomar `bytes` o un `str` que solo contenga caracteres ASCII (los carácteres en inglés), esto significa que no funcionaría con caracteres como `á`, como en `Sebastián`.

Para manejar eso, primero convertimos el `username` y `password` a `bytes` codificándolos con UTF-8.
