そのうえで、`secrets.compare_digest()` を使って、`credentials.username` が `"stanleyjobson"` であり、`credentials.password` が `"swordfish"` であることを確認します。

{* ../../docs_src/security/tutorial007_an_py310.py hl[1,12:24] *}

これは次のようなコードに相当します:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # 何らかのエラーを返す
    ...
```
