Django authパッケージのカスタムでパスワードがhash化されない

前提・実現したいこと

python Djangoで管理システムを構築しています。
ユーザー管理でauthパッケージをカスタムしているのですが、新規登録時と更新時にパスワードが暗号化されなく困っております。

python manage.py createsuperuser を叩くとhash化されますが、web上で更新/登録するとhash化されずにそのままテーブルに入ります。

forms.pyの修正やライブラリーなどを変えてみましたがpython初学者の為よく分かりません。

調べたところ forms.py か models.py に set_password() を書けば良さそうとあるのですが、どこにどう書けば良いか分かりませんでした。
どなたかご教示お願い致します。
