OpenAPI define os seguintes esquemas de segurança:

* `apiKey`: uma chave específica de aplicação que pode vir de:
    * Um parâmetro query.
    * Um header.
    * Um cookie.
* `http`: padrão HTTP de sistemas autenticação, incluindo:
    * `bearer`: um header de `Authorization` com valor de `Bearer` adicionado de um token. Isso é herança do OAuth2.
