django-pwned-passwords is a Django password validator that checks Troy Hunt's PWNED Passwords API to see if a password has been involved in a major security breach before.

Note: This app currently sends a portion of a user's hashed password to a third party. Before using this application, you should understand how that impacts you.

Documentation

The full documentation is at https://django-pwned-passwords.readthedocs.io.

Requirements

• Django [1.9, 2.1]
• Python 2.7, [3.5, 3.6, 3.7]

Quickstart

Install django-pwned-passwords::

pip install django-pwned-passwords

Add it to your INSTALLED_APPS:

.. code-block:: python

INSTALLED_APPS = (
    ...
    'django_pwned_passwords',
    ...
)

Add django-pwned-passwords's PWNEDPasswordValidator:

.. code-block:: python

AUTH_PASSWORD_VALIDATORS = [
    ...
    {
        'NAME': 'django_pwned_passwords.password_validation.PWNEDPasswordValidator'
    }
]

Features

This password validator returns a ValidationError if the PWNED Passwords API detects the password in its data set. Note that the API is heavily rate-limited, so there is a timeout (:code:PWNED_VALIDATOR_TIMEOUT).

If :code:PWNED_VALIDATOR_FAIL_SAFE is True, anything besides an API-identified bad password will pass, including a timeout. If :code:PWNED_VALIDATOR_FAIL_SAFE is False, anything besides a good password will fail and raise a ValidationError.

Rate Limiting

Historically, requests to the API were rate limited. However, with the new k-anonymity model-based API, there are no such rate limits.
