title: Installing Jenkins the first time and do not know the default user name
body: <p>I tried using Jenkins or my admin username as <code>user</code> and <code>password</code>. For password, I tried to update using <code>sudo passwd jenkins</code>, so I am fine on that. However, I am skeptical about the user name. How do I confirm the username for Jenkins? Can someone pls help me?</p>
