django 1.9 createsuperuser bypass the password validation checking
You can change the AUTH_PASSWORD_VALIDATORS setting in in your dev environment. See the docs: https://docs.djangoproject.com/en/stable/topics/auth/passwords/#s-enabling-password-validation.
It is pretty straightforward: you will recognize the validators that caused your warning messages.
In fact, you do not need to modify the validator settings or first create a complex password and then later change it. Instead you can create a simple password directly bypassing all password validators.
Open the django shell
python manage.py shell
Type:
from django.contrib.auth.models import User
Hit enter and then type (e.g. to use a password consisting only of the letter 'a'):
User.objects.create_superuser('someusername', 'something@example.com', 'a')
Hit enter again and you're done.
