Se você não se importa com qualquer um desses termos e só precisa adicionar segurança com autenticação baseada em usuário e senha _agora_, pule para os próximos capítulos.

## OAuth2

OAuth2 é uma especificação que define várias formas para lidar com autenticação e autorização.

Ela é bastante extensiva na especificação e cobre casos de uso muito complexos.

Ela inclui uma forma para autenticação usando “third party”/aplicações de terceiros.

#### OpenAPI y JSON Schema

OpenAPI define un esquema de API para tu API. Y ese esquema incluye definiciones (o "esquemas") de los datos enviados y recibidos por tu API utilizando **JSON Schema**, el estándar para esquemas de datos JSON.
