* **입력 모델** 은 비밀번호를 가져야 합니다.

절대 사용자의 비밀번호를 평문으로 저장하지 마세요. 항상 이후에 검증 가능한 "안전한 해시(secure hash)"로 저장하세요.

만약 이게 무엇인지 모르겠다면, [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.에서 비밀번호 해시에 대해 배울 수 있습니다.

## 다중 모델

아래는 비밀번호 필드와 해당 필드가 사용되는 위치를 포함하여, 각 모델들이 어떤 형태를 가질 수 있는지 전반적인 예시입니다:

::: fastapi.security.APIKeyCookie

::: fastapi.security.APIKeyHeader

::: fastapi.security.APIKeyQuery

## HTTP Authentication Schemes

::: fastapi.security.HTTPBasic

::: fastapi.security.HTTPBearer

::: fastapi.security.HTTPDigest

## HTTP Credentials

::: fastapi.security.HTTPAuthorizationCredentials

::: fastapi.security.HTTPBasicCredentials

## OAuth2 Authentication

# Security { #security }

There are many ways to handle security, authentication and authorization.

And it normally is a complex and "difficult" topic.

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).

But when you want to also declare OAuth2 scopes, you can use `Security()` instead of `Depends()`.

You can import `Security()` directly from `fastapi`:

```python
from fastapi import Security
```

## Scopes in *Pfadoperationen* und Abhängigkeiten deklarieren

Jetzt deklarieren wir, dass die *Pfadoperation* für `/users/me/items/` den Scope `items` erfordert.

Dazu importieren und verwenden wir `Security` von `fastapi`.
