	**FastAPI** saberá que pode usar a classe `OAuth2PasswordBearer` (declarada na dependência) para definir o esquema de segurança na OpenAPI porque herda de `fastapi.security.oauth2.OAuth2`, que por sua vez herda de `fastapi.security.base.Securitybase`.

	 Todos os utilitários de segurança que se integram com OpenAPI (e na documentação da API automática) herdam de `SecurityBase`, é assim que **FastAPI** pode saber como integrá-los no OpenAPI.

## O que ele faz

## Review PRs

If a PR doesn't explain what it does or why, ask for more information.

A PR should have a specific use case that it is solving.

* If the PR is for a feature, it should have docs.
    * Unless it's a feature we want to discourage, like support for a corner case that we don't want users to use.
* The docs should include a source example file, not write Python directly in Markdown.
