title: Where does vscode extensions store login information?
body: <p>I have a few extensions where I have logged in to an online service like Azure Account and Docker Hub.</p>
  
  <p>Each time I start VSCode, I am able to use these services, which is great.</p>
  
  <p>But, how is this login-info stored? Will I have to go through each of them and logout, or are there some settings etc. that I can delete, to make sure I am logged out of everything?</p>
  
  <p>What if I delete extensions? Is the login-info still there, so that if the extension is re-installed, it will be immediately logged in?</p>
