Set
`required=False`<https://docs.djangoproject.com/en/dev/ref/forms/fields/#django.forms.Field.required>on
your `password` field`.
If you want to make sure it's only non-mandatory when the user exists
override your `UserForm.__init__` this way:
class UserForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
def __init__(self, *args **kwargs):
super(UserForm, self).__init__(*args, **kwargs)
self.fields['password'].required = self.instance.pk is None
....
