title: Django Python change user default attributes for authentication
body: <p>In Django, the default attributes for user:
  username
  password
  email
  first_name
  last_name</p>
  
  <p>I would like to remove email, first_name, last_name 
  and replace it with company</p>
  
  <p>Is that possible ? Can someone show me the process of performing an authentication session with these 3 modified attributes:
  - company
  - username
  - password</p>
  
  <p>Thanks.</p>
