title: python-jira login without password? Any possible way to create encrypted token and use in lieu password?
body: <p>Below is python test code to login <code>jira</code> using username and password and it works fine.</p>
  
  <pre><code>from jira import JIRA
  
  jira = JIRA('http://xxx')
  jira = JIRA(basic_auth=('username','password'),options={'server': 'http://xxx'})
  
  issue = jira.issue('XXXX-762')
  
  print "For task", issue,", summary is-", issue.fields.summary
  </code></pre>
  
  <p>Now I require to log in <code>jira</code> without using password.
  can anyone help?</p>
  
  <p>Aim of this is to hide the password in general script and also make the script independent of jira password expiry.</p>
  
  <p>Jira version used: JIRA v7.5.2</p>
