FastAPI stands on the shoulders of giants:

# 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`.

Nos capítulos sobre segurança, existem funções utilitárias que são implementadas desta maneira.

Se você entendeu tudo isso, você já sabe como essas funções utilitárias para segurança funcionam por debaixo dos panos.

## Context

Modern best practices when developing a Gradle plugin are to use lazy types (ConfigurableFileCollection, Provider API, domain object containers) when defining configurable parts of a plugin (tasks, extensions, domain objects).  The Provider API provides a consistent way to set conventions, wire related configuration together (extension <- domain object <- task) and avoid evaluation ordering problems.
