For example, Google login uses OpenID Connect (which underneath uses OAuth2).

But Facebook login doesn't support OpenID Connect. It has its own flavor of OAuth2.

### OpenID (not "OpenID Connect") { #openid-not-openid-connect }

There was also an "OpenID" specification. That tried to solve the same thing as **OpenID Connect**, but was not based on OAuth2.

## `q` 매개변수의 타입에 `Annotated` 사용하기 { #use-annotated-in-the-type-for-the-q-parameter }

이전에 [Python 타입 소개](../python-types.md#type-hints-with-metadata-annotations)에서 `Annotated`를 사용해 매개변수에 메타데이터를 추가할 수 있다고 말씀드린 것을 기억하시나요?

이제 FastAPI에서 사용할 차례입니다. 🚀

다음과 같은 타입 어노테이션이 있었습니다:

```Python
q: str | None = None
```
