title: DotNetOpenAuth Resource Owner Password Credentials Grant Token Store
body: <p>I'm currently working on a small mobile project and I want to use DotNetOpenAuth to protect the API. I currently decided to use 4.3 of the OAuth 2.0 Spec "Resource Owner Password Credentials Grant".</p>
  
  <p>I downloaded the Samples and it has an Authorization Server sample which helped a lot so I managed to get everything working on that end. I authenticate the user with my custom auth provider using the CheckAuthorizeResourceOwnerCredentialGrant method. This later calls the CreateAccessToken method which return the Access Token successfully.</p>
  
  <p>Now I know I need to store the Token to authorize the user on later requests.</p>
  
  <p>That's where I'm a bit lost. Is there a way of doing this following DNOA best practices, without me having to bake this on my own? Maybe in the current samples?</p>
