### Security and authentication

Security and authentication integrated. Without any compromise with databases or data models.

All the security schemes defined in OpenAPI, including:

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* API keys in:

import com.google.common.testing.NullPointerTester;
import java.security.Key;
import java.util.Arrays;
import javax.crypto.Mac;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
import junit.framework.TestCase;
import org.checkerframework.checker.nullness.qual.Nullable;
import sun.security.jca.ProviderList;
import sun.security.jca.Providers;

この依存関係は、*path operation function*のパラメーター`token`に代入される`str`を提供します。

**FastAPI**は、この依存関係を使用してOpenAPIスキーマ (および自動APIドキュメント) で「セキュリティスキーム」を定義できることを知っています。

/// info | "技術詳細"

**FastAPI**は、`OAuth2PasswordBearer` クラス (依存関係で宣言されている) を使用してOpenAPIのセキュリティスキームを定義できることを知っています。これは`fastapi.security.oauth2.OAuth2`、`fastapi.security.base.SecurityBase`を継承しているからです。
