title: How does `az login` store credential information?
body: <p>I am wondering what happens when I am logging to azure using <code>az login</code> behind the scenes. I am still logged on for a long time, meaning that something is stored on the machine that allows access.</p>
  <p>Would it be possible for an adversary who gains access to the harddrive to read that password/token in clear text to impersonate me?</p>
  <p>P.S. I do not mean the credentials that are a part of the <code>az login</code> command itself, but data that is saved behind the scenes by the command.</p>
