#### 13.1.1.1. OAuth 2.0 Authorization Grant

The authorization code grant starts with the client, such as a web-based service, redirecting the resource owner's user-agent to the OpenAM authorization service. After authenticating the resource owner and obtaining the resource owner's authorization, OpenAM redirects the resource owner's user-agent back to the client with an authorization code that the client uses to request the access token. The following sequence diagram outlines a successful process from initial client redirection through to the client accessing the protected resource.
