# Simple OAuth2 with Password and Bearer { #simple-oauth2-with-password-and-bearer }

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.

# Simple OAuth2 con Password y Bearer { #simple-oauth2-with-password-and-bearer }

Ahora vamos a construir a partir del capítulo anterior y agregar las partes faltantes para tener un flujo de seguridad completo.

## Obtener el `username` y `password` { #get-the-username-and-password }

Vamos a usar las utilidades de seguridad de **FastAPI** para obtener el `username` y `password`.

# Simples OAuth2 com senha e Bearer { #simple-oauth2-with-password-and-bearer }

Agora vamos construir a partir do capítulo anterior e adicionar as partes que faltam para ter um fluxo de segurança completo.

## Obtenha o `username` e a `password` { #get-the-username-and-password }

É utilizado o utils de segurança da **FastAPI** para obter o `username` e a `password`.

# Einfaches OAuth2 mit Password und Bearer { #simple-oauth2-with-password-and-bearer }

Lassen Sie uns nun auf dem vorherigen Kapitel aufbauen und die fehlenden Teile hinzufügen, um einen vollständigen Sicherheits-Flow zu erhalten.

## `username` und `password` entgegennehmen { #get-the-username-and-password }

Wir werden **FastAPIs** Sicherheits-Werkzeuge verwenden, um den `username` und das `password` entgegenzunehmen.

# Простая авторизация OAuth2 с паролем и «Bearer» { #simple-oauth2-with-password-and-bearer }

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**.
