title: A user access token is required to request this resource
body: <p>I've developed a Facebookapp that has the "user_photos" permission. Now i've submitted the App, which is now live. I've installed it on several Facebook-Accounts of my friends... (Yes! they have granted the requested permissions)</p>
  
  <p>When i now try to make an request i get the following error message</p>
  
  <p><code>{
    "error": {
      "message": "A user access token is required to request this resource.",
      "type": "OAuthException",
      "code": 102
    }
  }
  </code></p>
  
  <p>Here's my Request-Query:
  <a href="https://graph.facebook.com/LogInIDOfMyFriendThatHasInstalledTheAPP/?fields=albums.fields(photos,name,description),email&amp;access_token=mySecretAppToken" rel="nofollow">https://graph.facebook.com/LogInIDOfMyFriendThatHasInstalledTheAPP/?fields=albums.fields(photos,name,description),email&amp;access_token=mySecretAppToken</a></p>
  
  <p>Ok it works if I replace the App-Token with a User-Token that is generated by an OAuth-Process or via GraphAPIExplorer but in the Documentation (<a href="https://developers.facebook.com/docs/facebook-login/access-tokens/" rel="nofollow">https://developers.facebook.com/docs/facebook-login/access-tokens/</a>) it is said (in Paragraph) "App Tokens" that
  "App access tokens are used to make requests to Facebook APIs on behalf of an app rather than a user. [...]" and that i have to generate an other "App Accesstoken" but this also does't work.</p>
  
  <p>I'm confused...</p>
  
  <p>So is there something i've forgotten / missunderstood or do I have to use the oAuth-Way which means that my friends have to reauthenticate to my App every two month???</p>
  
  <p>Thanks a lot!</p>
  
  <p>Best regards
    Mike</p>
