## Hash and verify the passwords { #hash-and-verify-the-passwords }

Import the tools we need from `pwdlib`.

Create a PasswordHash instance with recommended settings - it will be used for hashing and verifying passwords.

Вы можете использовать весь функционал <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a> и в `FastAPI`.

### Шаг 2: создайте экземпляр `FastAPI` { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py39.py hl[3] *}

Здесь переменная `app` будет экземпляром класса `FastAPI`.

Это будет основная точка взаимодействия для создания всего вашего API.
