# JWT Authentication

### HOW the JWT Authentication flow works

The JWT-based flow works through two essential types of tokens:

* [**Access Token**](https://docs.zapsign.com.br/english/authentication/jwt-authentication/get-access-token)
* [**Refresh Token**](https://docs.zapsign.com.br/english/authentication/jwt-authentication/refresh-your-access-token)

With these two tokens, **you will be able to authenticate with ZapSign and integrate with your application.** In the following chapters, we will discuss each token in more detail.
