There is an example here: https://docs.djangoproject.com/en/2.1/topics/auth/default/#changing-passwords

If you want the code you posted to work, you can use set_password() on the User.

user.set_password('new password')
user.save()

But, as Timmy O'Mahony said, it's better to use https://docs.djangoproject.com/en/2.1/topics/auth/default/#module-django.contrib.auth.forms
