title: Xamarin Authentication Version control operation failed when connecting to github
body: <p>I'm trying to publish some code to my GitHub repository from within Xamarin Studio 5.1</p>
  
  <p>When I first did the publish it prompted me for my Username and Password which I entered but I made a type in my password.
  Now whenever I try to publish I get the error:</p>
  
  <pre><code>NGit.Errors.TransportException: https://github.com:443/xxx/yyy: not authorized
     at NGit.Api.FetchCommand.Call()
     at MonoDevelop.VersionControl.Git.GitRepository.OnPublish(String serverPath, FilePath localPath, FilePath[] files, String message, IProgressMonitor monitor)
     at MonoDevelop.VersionControl.Repository.Publish(String serverPath, FilePath localPath, FilePath[] files, String message, IProgressMonitor monitor)
     at MonoDevelop.VersionControl.PublishWorker.Run()
     at MonoDevelop.VersionControl.Task.BackgroundWorker(Object state)
  </code></pre>
  
  <p>And I don't get prompted to re-enter my password.</p>
  
  <p>I've read from here about deleting the KeyChain:

  <p>I thought the equivalent of the KeyChain app was the Windows Credentials Manager and I've deleted a few things from there that look as though they may be relevant and restarted Xamarin but I'm still not getting prompted for my password.</p>
  
  <p>Any suggestions?</p>
