title: Facebook unattended access for multiple accounts
body: <p>My application will be used to read the walls of up to 20 Facebook pages and also to post and perform other authenticated activities on behalf of those pages.</p>
  
  <p>Retrieving the wall posts is easily possible via the graph API.  However, posting and doing other things on behalf of each of these users is where my question lies.  </p>
  
  <p>A bit more background:</p>
  
  <p>The app will have users who will drive the sending of messages.  These users will be happy to grant access to our app manually as a one off exercise, but  but they do not want to log in every time they run the app. </p>
  
  <p>The question:</p>
  
  <p>I want to collect the login/password details <em>once</em> during installation - and for the applications server to handle the token request, posting activities and other things thereafter in an 'unattended' manner.  Is this possible - and if so, how?  </p>
  
  <p>Thanks in advance.</p>
