title: Send password in welcome email in Django
body: <p>I have a script that creates multiple users based on an excel file, and a signal that sends out a welcome email to the user. I'd like that welcome email to also include the password in plain text. I know it's not good practice and I should send the user a link to set their password, but time is unfortunately not on my side right now.</p>
  
  <p>Is there a way to have the plain text password in the <code>post_save</code> signal?</p>
