Creating a user with django-zxcvbn-password-validator
If the password is not strong enough, we provide errors explaining what you need to do :
The error message are translated to your target language (even the string given by zxcvbn that are in english only) :
How to use
Add django-zxcvbn-password-validator
to your requirements and get it with
pip. Then everything happens in your settings file.
Add 'django_zxcvbn_password_validator'
in the INSTALLED_APPS
:
INSTALLED_APPS = [
# ...
'django_zxcvbn_password_validator'
]
Modify AUTH_PASSWORD_VALIDATORS
:
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
'NAME': 'django_zxcvbn_password_validator.ZxcvbnPasswordValidator',
},
# ...
]
You could choose to use zxcvbn alone, but I personally still use Django's UserAttributeSimilarityValidator
,
because there seems to be still be some problem with it integrating user
informations with zxcvbn (as of june 2018).
Finally you can set the PASSWORD_MINIMAL_STRENGTH
to your liking (default
is 2), every password scoring lower than this number will be rejected :
# 0 too guessable: risky password. (guesses < 10^3)
# 1 very guessable: protection from throttled online attacks.
# (guesses < 10^6)
# 2 somewhat guessable: protection from unthrottled online attacks.
# (guesses < 10^8)
# 3 safely unguessable: moderate protection from offline slow-hash scenario.
# (guesses < 10^10)
# 4 very unguessable: strong protection from offline slow-hash scenario.
# (guesses >= 10^10)
