title: Changing COLAB main account. How to change which email / drive my colab should be linked to?
body: <p>I have two accounts on gmail and both are open at the same time: Account_1@gmail.com and Account_2@gmail.com</p>
  <p>When I open <a href="https://colab.research.google.com/" rel="nofollow noreferrer">https://colab.research.google.com/</a> and paste a github link, the colab connects to Account_1@gmail.com by default.</p>
  <p>How do I change settings so that each time i open Colab it links to Account_2@gmail.com?</p>
  <ul>
  <li>What I have tried*</li>
  </ul>
  <ol>
  <li>I seem to get around this when i open a colab file from github and then when saving the file as, i change the gmail account at the top right before.</li>
  <li>I've tried looking for settings in Colab that allow me to register a  'main' email account but i dont see to find this.</li>
