## Recapitulando { #recap }

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".
