# Simples OAuth2 com senha e Bearer

Agora vamos construir a partir do capítulo anterior e adicionar as partes que faltam para ter um fluxo de segurança completo.

## Pegue o `username` (nome de usuário) e `password` (senha)

É utilizado o utils de segurança da **FastAPI** para obter o `username` e a `password`.
