# Segurança - Primeiros Passos

Vamos imaginar que você tem a sua API **backend** em algum domínio.

E você tem um **frontend** em outro domínio ou em um path diferente no mesmo domínio (ou em uma aplicação mobile).

E você quer uma maneira de o frontend autenticar o backend, usando um **username** e **senha**.

Nós podemos usar o **OAuth2** junto com o **FastAPI**.
