django2.2.6 check_password 验证失败解决办法（重设密码）

python3.6, django 2.2.6 AUTHENTICATION_BACKENDS 里添加自定义认证 CustomBackend（邮箱、手机号等），

用 python manage.py createsuperuser 创建的超级管理员登录时密码一直验证失败(False)

# 用户名之外的唯一值字段也能用来登录，setting 里要有对应的配置 AUTHENTICATION_BACKENDS
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            # 邮箱、用户名、手机号码 登录
            user = UserProfile.objects.get(Q(username=username) | Q(email=username) | Q(phone=username))
            # user_check_password = user.check_password(password)
            user_check_password = check_password(password, user.password)
            if user_check_password:
                return user
        except User.DoesNotExist:
            return None

# settings.py

AUTH_USER_MODEL = 'users.UserProfile'  # 重载系统的用户，让 UserProfile 生效

# AUTH 方法（支持邮箱、手机号等登录）, 验证从上到下
AUTHENTICATION_BACKENDS = (
    'apps.users.backends.other.CustomBackend',
    # 'social_core.backends.weibo.WeiboOAuth2',
    # 'social_core.backends.qq.QQOAuth2',
    # 'social_core.backends.weixin.WeixinOAuth2',
    # 'social_core.backends.github.GithubOAuth2',
    # 'social_core.backends.gitlab.GitLabOAuth2',
    # 'django.contrib.auth.backends.ModelBackend',
)

删库重建无数次都不行，突然想到用 shell 重新设置密码一次，果然就登录上去了。（这段代码也是修改超级管理密码的过程）
