You also need to register your model like this to include the password setting into your user creation flow in the admin panel:

# -*- coding: utf-8 -*- from __future__ import unicode_literals

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from users import models

admin.site.register(models.MyUser, UserAdmin)
