How do I set my user password on my Google Cloud Ubuntu instance?
<p>I have started an Ubuntu 15.10 instance on Google Cloud and installed Webmin as per here:</p>

<p><a href="http://www.webmin.com/deb.html" rel="noreferrer">http://www.webmin.com/deb.html</a></p>

<p>Webmin has been installed successfully and I can see the login page in my browser window, however I need to type my username along with my password with sudo level access to login and start using Webmin.  </p>

<p>I've used the SSH via the browser window so have never set a password for any sort of access to the root.</p>

<p>Does anyone know how to set a password for myself to login as a sudo user on my instance?</p>
