django-password-policies-validator
==================================
django-password-policies-validator is a Django app to validate password complexity and prevent users from reusing previous passwords.
Quick start
-----------
#. Add "password_policies" to your INSTALLED_APPS setting like this::
INSTALLED_APPS = [
...
'password_policies',
]
#. Add validators to AUTH_PASSWORD_VALIDATORS setting::
AUTH_PASSWORD_VALIDATORS = [
...
{
'NAME': 'password_policies.password_validation.ComplexityValidator',
},
{
'NAME': 'password_policies.password_validation.ReusedPasswordValidator',
},
{
'NAME': 'password_policies.password_validation.MinimumChangeIntervalValidator',
},
]
#. Append ``PasswordExpirationMiddleware`` to MIDDLEWARE setting, note that this must be listed **after** the ``'django.contrib.auth.middleware.AuthenticationMiddleware'`` ::
MIDDLEWARE = [
...
'password_policies.middleware.PasswordExpirationMiddleware',
]
#. Run ``python manage.py migrate`` to create the ``PasswordRecord`` models.
#. Start the development server and go to the "Change password" page to check how the new password policies applied.
The ``Validator`` classes
-------------------------
Custom options can be passed into validators by the following syntax ::
AUTH_PASSWORD_VALIDATORS = [
...
{
'NAME': 'password_policies.password_validation.ComplexityValidator',
'OPTIONS': {
'min_char_categories': 3,
'min_numeric_chars': 2,
}
},
]
Available options of each validator and their default values are listed below.
``ComplexityValidator(min_char_categories=4, min_numeric_chars=1, min_uppercase_chars=1, min_lowercase_chars=1, min_special_chars=1)``
Validates that the password is complex enough by checking how many categories of characters it contains, or the count of certain category of characters. Characters are devided into four categories:
- Uppercase alphabet characters A-Z
- Lowercase alphabet characters a-z
- Numeric characters 0-9
- Non-alphanumeric (special) characters
``min_char_categories``
The minimum categories of characters that the password should contain out of the four categories above. Value should be between 1 and 4.
``min_numeric_chars``
The minimum count of numeric characters that the password should contain. Value should be 0 or any positive integer.
``min_uppercase_chars``
The minimum count of uppercase characters that the password should contain. Value should be 0 or any positive integer.
``min_lowercase_chars``
The minimum count of lowercase characters that the password should contain. Value should be 0 or any positive integer.
``min_special_chars``
The minimum count of special characters that the password should contain. Value should be 0 or any positive integer.
``ReusedPasswordValidator(record_length=3)``
Remembers the user's previous *n* passwords and validate the new password doed not repeat any of them.
``record_length``
The number of previous password records that the validator should compare against. Value should be any positive integer.
``MinimumChangeIntervalValidator(min_interval=1)``
Prevent the user from changing the password again within certain period of time. This is to avoid the user to bypass ``ReusedPasswordValidator`` and reuse the old password by changing passwords repeatedly in a short period of time.
``min_interval``
The minimum time interval (in days) of two consecutive password change attempts. Value should be any positive interger or float.
The ``PasswordExpirationMiddleware`` class
------------------------------------------
``PasswordExpirationMiddleware``
Checks the user's password-changing records, if the user's password is expired, redirect the user to the password-changing form and shows a warning message.
This middleware works for any urls under the ``admin`` application namespace and redirects to the ``password_change`` url under the same namespace of the page which the user is redirected from. Urls not under the ``admin`` application namespace are not redirected.
The password expires in 90 days by default, and the number can be set by providing setting ``PASSWORD_EXPIRATION_DAYS`` to an integer or float value in ``settings.py``.
