## Recaptulando

Agora você tem as ferramentas para implementar um sistema de segurança completo baseado em `username` e `password` para sua API.

Usando essas ferramentas, você pode tornar o sistema de segurança compatível com qualquer banco de dados e com qualquer usuário ou modelo de dados.

O único detalhe que falta é que ainda não é realmente "seguro".

Isso ocorre por que, por padrão, o FastAPI irá verificar cada item dentro do dicionário e garantir que ele seja serializável para JSON, utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.
