Installation

pip install django-zxcvbn-password

Usage

# settings.py

AUTH_PASSWORD_VALIDATORS = [{
    'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
}, {
    'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
}, {
    'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
}, {
    'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
}, {
    'NAME': 'zxcvbn_password.ZXCVBNValidator',
    'OPTIONS': {
        'min_score': 3,
        'user_attributes': ('username', 'email', 'first_name', 'last_name')
    }
}]

# forms.py

from django import forms
from zxcvbn_password.fields import PasswordField, PasswordConfirmationField

class RegisterForm(forms.Form):
    password1 = PasswordField()
    password2 = PasswordConfirmationField(confirm_with=’password1’)

Note

Remember to include {{ form.media }} in your template. Please refer to the documentation of the two upstream repositories for more information.

By default, other inputs won’t be used to compute the score, but you can enforce it like this:

# forms.py

from zxcvbn_password import zxcbnn

# in your form class
def clean():
    password = self.cleaned_data.get('password')
    other_field1 = ...
    other_field2 = ...

    if password:
        score = zxcvbn(password, [other_field1, other_field2])['score']
        # raise forms.ValidationError if needed

    return self.cleaned_data
