So, as e4c5 mentioned, it is really simple and straightforward.

My CustomPasswordValidator looks like this: 

from django.core.exceptions import ValidationError
from django.utils.translation import ugettext as _

class CustomPasswordValidator():

    def __init__(self, min_length=1):
        self.min_length = min_length

    def validate(self, password, user=None):
        special_characters = "[~\!@#\$%\^&\*\(\)_\+{}\":;'\[\]]"
        if not any(char.isdigit() for char in password):
            raise ValidationError(_('Password must contain at least %(min_length)d digit.') % {'min_length': self.min_length})
        if not any(char.isalpha() for char in password):
            raise ValidationError(_('Password must contain at least %(min_length)d letter.') % {'min_length': self.min_length})
        if not any(char in special_characters for char in password):
            raise ValidationError(_('Password must contain at least %(min_length)d special character.') % {'min_length': self.min_length})

    def get_help_text(self):
        return ""

Just add it to the list of AUTH_PASSWORD_VALIDATORS in settings.py and that’s it!

AUTH_PASSWORD_VALIDATORS = [
{
    'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
    'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
},
{
    'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
},
{
    'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
},
{   'NAME': 'registration.validators.CustomPasswordValidator',

},]
