django-password-rotate 1.0.1

Django app for forcing password rotation

Django password rotation app

This app provides configurable rotation of passwords.

Features

• Configurable password duration and warning duration
• Visual warning to user using Django messages
• Prevents user from accessing any page in after expiration unless the password is changed
• Forces the new password to be different from previously used passwords
• Prevents similar passwords (ex: "password1", "password2", ...)

Requirements

This Django app requires Python >= 3.8 and has been tested with Django 4.2, 5.1 and 5.2.

Installation

1. pip install django-password-rotate.
2. Add password_rotate to INSTALLED_APPS.
3. Add 'password_rotate.middleware.PasswordRotateMiddleware' to MIDDLEWARE. It should be listed after authentication and session middlewares.
4. Add password_rotate.validators.NotPreviousPasswordValidator to AUTH_PASSWORD_VALIDATORS:

AUTH_PASSWORD_VALIDATORS = [
...
{
    "NAME": "password_rotate.validators.NotPreviousPasswordValidator",
},
]

5. Add the pattern in the urls of your project:

urlpatterns = [
    ...
    path("password_rotate/", include("password_rotate.urls")),
]

6. Configure the app in your settings:

   # rotate passwords after 90 days
   PASSWORD_ROTATE_SECONDS = 90 * 24 * 60 * 60
   # start warning 10 days before expiration
   PASSWORD_ROTATE_WARN_SECONDS = 10 * 24 * 60 * 60
   # keep at most the 3 previous (encrypted) passwords
   PASSWORD_ROTATE_HISTORY_COUNT = 3
   # when changing the password, allow only a new password with similarity ratio greater than 50
   PASSWORD_ROTATE_MAX_SIMILARITY_RATIO = 50
   

7. Run python manage.py migrate to create the required database tables.

If you want to exclude superusers from the password expiration, set this flag:

PASSWORD_ROTATE_EXCLUDE_SUPERUSERS = True
