title: How can I get firebase deploy --email or --token parameters to work?
body: <p>I'm having trouble deploying travis CI with firebase using these firebase commands:</p>
  
  <pre><code>firebase deploy --email ${FIREBASE_USERNAME} --password ${FIREBASE_PASSWORD}
  firebase deploy --token ${FIREBASE_TOKEN}
  </code></pre>
  
  <p>It does not like <code>--email</code> option and it does seem that it takes <code>--token</code> but does not work with my firebase auth token I can get from my firebase app. What am I doing wrong?</p>
