Configuration

You can configure minimum and maximum length of the password, and the minimum entropy (refer to zxcvbn documentation for more details). The following values are the default:

# settings.py

PASSWORD_MIN_LENGTH = 8
PASSWORD_MAX_LENGTH = 128
PASSWORD_MIN_ENTROPY = 25

You can also configure the messages that are displayed when one of these criteria is not respected. For minimum and maximum length messages, you may use a %s: it will take the value of the minimum / maximum length. These options are optional, there already are default messages.

# settings.py

from django.utils.translation import ugettext_lazy as _

PASSWORD_MIN_LENGTH_MESSAGE = _("Please use at least %s characters!")
PASSWORD_MAX_LENGTH_MESSAGE = _("Wow, there are too much now! The maximum is %s.")
PASSWORD_MIN_ENTROPY_MESSAGE = _("The complexity of your password is not sufficient...")
