А точніше, використовуючи безпосередньо `user_dict`, з будь-яким його вмістом у майбутньому:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

Üçüncü taraf uygulamalar ve sistemler tarafından kullanılabilir.

Ve aynı uygulamayı debug etmek, kontrol etmek ve test etmek için sizin tarafınızdan da kullanılabilir.

## `password` Flow { #the-password-flow }

Şimdi biraz geri dönüp bunların ne olduğuna bakalım.

`password` "flow"u, OAuth2’de güvenlik ve authentication’ı yönetmek için tanımlanmış yöntemlerden ("flow"lardan) biridir.

        TermQueryBuilder builder = regTermQ("password", password);
        if (opLambda != null) {
            opLambda.callback(builder);
        }
    }

    public void setPassword_NotEqual(String password) {
        setPassword_NotTerm(password, null);
    }

    public void setPassword_NotTerm(String password) {
        setPassword_NotTerm(password, null);

Теперь, отталкиваясь от предыдущей главы, добавим недостающие части, чтобы получить полный поток безопасности.

## Получение `username` и `password` { #get-the-username-and-password }

Для получения `username` и `password` мы будем использовать утилиты безопасности **FastAPI**.

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

O más exactamente, usando `user_dict` directamente, con cualquier contenido que pueda tener en el futuro:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

errors.invalid_str_is_included = {0} non è valido in {1}.
errors.blank_password = La password è obbligatoria.
errors.password_length = La password deve contenere almeno {0} caratteri.
errors.password_no_uppercase = La password deve contenere almeno una lettera maiuscola.
errors.password_no_lowercase = La password deve contenere almeno una lettera minuscola.
errors.password_no_digit = La password deve contenere almeno una cifra.

    }

    /**
     * Changes the password for a user across all authentication chains.
     * @param username The username for which to change the password.
     * @param password The new password.
