## OAuth2 { #oauth2 }

OAuth2 ist eine Spezifikation, die verschiedene Möglichkeiten zur Handhabung von Authentifizierung und Autorisierung definiert.

Es handelt sich um eine recht umfangreiche Spezifikation, und sie deckt mehrere komplexe Anwendungsfälle ab.

Sie umfasst Möglichkeiten zur Authentifizierung mithilfe eines „Dritten“ („third party“).

Plugins Bindings for <<<default>>> Lifecycle Reference

  The {{{./lifecycles.html}<<<default>>> lifecycle}} is defined without any plugin binding; plugins bindings are defined separately
  in {{{./apidocs/org/apache/maven/lifecycle/providers/packaging/package-summary.html}<<<org.apache.maven.lifecycle.providers.packaging>>>}} package
  because they are specific for each packaging:

{* ../../docs_src/request_form_models/tutorial001_an_py39.py hl[9:11,15] *}

O **FastAPI** irá **extrair** as informações para **cada campo** dos **dados do formulário** na requisição e dar para você o modelo Pydantic que você definiu.
