# OAuth

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

OAuth 2.0 is the industry-standard protocol for authorization. OAuth 2.0 focuses on client developer
simplicity while providing specific authorization flows for web applications, desktop applications,
mobile phones, and livingroom devices. For more information about the OAuth 2.0 protocol, see
[https://oauth.net/2/](https://oauth.net/2/).

The SDK provides support for building modules that are OAuth enabled, which means that they
establish connections that are authorized through the OAuth protocol. This enables you to hide most
of the complexities of the OAuth protocol from the end user and to spare them the requirement of
learning OAuth.

OAuth support provided by the SDK is limited to:

- OAuth version 2.

- [Authorization Code](https://docs.mulesoft.com/mule-sdk/latest/authorization-code) grant type

- [Client Credentials](https://docs.mulesoft.com/mule-sdk/latest/client-credentials) grant type (available since version 1.3)
