title: SP2013 incorrect credential cached in VS2012
body: <p>When I try to deploy to SP2013 I get the following error:</p>
  
  <pre><code>Error occurred in deployment step 'Install app for SharePoint': The System Account cannot perform this action
  </code></pre>
  
  <p>At some point earlier in time I put the farm setup user details into a login popup for the remote site. Unfortunately these details are cached somewhere and I cannot find where or update them.</p>
  
  <p>Anyone enlighten me as to where they reside?</p>
