Then we can use `secrets.compare_digest()` to ensure that `credentials.username` is `"stanleyjobson"`, and that `credentials.password` is `"swordfish"`.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

This would be similar to:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```

Dann können wir `secrets.compare_digest()` verwenden, um sicherzustellen, dass `credentials.username` `"stanleyjobson"` und `credentials.password` `"swordfish"` ist.

{* ../../docs_src/security/tutorial007_an_py39.py hl[1,12:24] *}

Dies wäre das gleiche wie:

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Einen Error zurückgeben
    ...
```
