A Django password validator using the Pwned Passwords API to check for compromised passwords.

Project description

Django Pwned

A collection of django password validators.


  • Python: 3.6, 3.7, 3.8, 3.9, 3.10
  • Django: 3.2, 4.0


pip install django-pwned

For translations to work, add django_pwned to INSTALLED_APPS.


    {"NAME": "django.contrib.auth.password_validation.UserAttributeSimilarityValidator"},
    {"NAME": "django_pwned.validators.GitHubLikePasswordValidator"},
    {"NAME": "django_pwned.validators.MinimumUniqueCharactersPasswordValidator"},
    {"NAME": "django_pwned.validators.PwnedPasswordValidator"},



This validator uses the Pwned Passwords API to check for compromised passwords.

Internally, this validator checks password with django's CommonPasswordValidator and if password was not in django's list, uses Pwned API to check password. So you can remove CommonPasswordValidator if you're using this validator.

    # ...
    # {"NAME": "django.contrib.auth.password_validation.CommonPasswordValidator"},
    {"NAME": "django_pwned.validators.PwnedPasswordValidator"},
    # ...

You can set the API request timeout with the request_timeout parameter (in seconds).

If for any reason (connection issues, timeout, ...) the request to Pwned API fails, this validator skips checking password.

GitHubLikePasswordValidator(min_length=8, safe_length=15)

Validates whether the password is at least:

  • 8 characters long, if it includes a number and a lowercase letter, or
  • 15 characters long with any combination of characters

Based on Github's documentation about creating a strong password.

You may want to disable Django's NumericPasswordValidator and MinimumLengthValidator if you want to use GitHubLikePasswordValidator.

The minimum number of characters can be customized with the min_length parameter. The length at which we remove the restriction about requiring both number and lowercase letter can be customized with the safe_length parameter.


Validates whether the password contains at least 4 unique characters. For example aaaaaaaaaabbbbbbccc is an invalid password, but aAbB is a valid password.

The minimum number of unique characters can be customized with the min_unique_characters parameter.
