pip install django-otp
and add ‘django_otp, django_otp.plugins.otp_totp‘ in our installed apps and django_otp.middleware.OTPMiddleware in middleware section of our settings file.
Python3
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_otp', 'django_otp.plugins.otp_totp' ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django_otp.middleware.OTPMiddleware'] |

Python3
SECURE_SSL_REDIRECT = TrueSESSION_COOKIE_SECURE = TrueSESSION_COOKIE_SECURE = TrueSECURE_BROWSER_XSS_FILTER = TrueSECURE_HSTS_SECONDS = 31536000SECURE_HSTS_INCLUDE_SUBDOMAINS = TrueSECURE_HSTS_PRELOAD = TrueSECURE_CONTENT_TYPE_NOSNIFF = TrueCSRF_COOKIE_SECURE = True |
