title: Firebase Error: Authentication required with firebase-tools
body: <p>I've just installed the firebase-tools with the as usual npm package installation process : </p>
  
  <pre><code>npm install -g firebase-tools 
  </code></pre>
  
  <p>i've already created a Firebase account connect with Google Account, but the problem is that the only procedure i can made with the command line tool is : </p>
  
  <pre><code>firebase login          // with success 
  firebase prefs:token    // return me the auth token 
  </code></pre>
  
  <p>but every time i try the other commands i get the error : </p>
  
  <pre><code>Error: Authentication required. 
  </code></pre>
  
  <p>for example for the command init, list etc : </p>
  
  <pre><code>firebase init         // error 
  firebase list         // error 
  </code></pre>
