⚙️ Installation

pip install django-sauth

---

🔧 Setup

1. Add to INSTALLED_APPS

# --------------------------------------------------
#  🔐 AUTHENTICATION & SAUTH CONFIG
# --------------------------------------------------
INSTALLED_APPS += [
    'django_sauth', # install here
    'axes', 
    'django_ratelimit',
    'users', # apps for custom user model
]

---

2. URLs

urlpatterns = [
    # admin
    path('admin/', admin.site.urls),

    # SAUTH URLs
    path('auth/', include('django_sauth.urls')), # Include SAUTH URLs

    # 👤 Role Dashboards
    path('dashboard/admin/', main_views.admin_dashboard),
    path('dashboard/', main_views.user_dashboard),
]

---

3. Required Settings

AUTH_USER_MODEL = 'users.CustomUser'

LOGIN_URL = 'sauth:login'

SAUTH = {
    "LOGIN_REDIRECT": "/dashboard/",
    "LOGOUT_REDIRECT": "/auth/login/",
    "ROLES": {
        "admin": "/dashboard/admin/",
        "user": "/dashboard/",
    },
}

---

🔐 Security Configuration (MANDATORY)

Password Hashing

# --------------------------------------------------
# 🔑 PASSWORD HASHERS (UPGRADE)
# --------------------------------------------------
PASSWORD_HASHERS = [
    'django.contrib.auth.hashers.Argon2PasswordHasher',  # 🔥 strongest
    'django.contrib.auth.hashers.PBKDF2PasswordHasher',
]

---

Rate Limiting (Redis)

# --------------------------------------------------
#  🔐 AUTHENTICATION BACKENDS & RATE LIMITING
# --------------------------------------------------
# Rate limiting (for login/register)
RATELIMIT_VIEW = 'ratelimit.views.RatelimitView'
RATELIMIT_USE_CACHE = 'default'
AUTHENTICATION_BACKENDS = [
    'axes.backends.AxesStandaloneBackend',
    'django.contrib.auth.backends.ModelBackend',
]

# --------------------------------------------------
# 🗄️ CACHE (Required for django-ratelimit)
# --------------------------------------------------
REDIS_REQUIRED = os.getenv("REDIS_REQUIRED", "False").lower() == "true"
REDIS_URL = os.getenv('REDIS_URL', 'redis://127.0.0.1:6379/1')
if REDIS_REQUIRED and not DEBUG:
    if not REDIS_URL:
        raise ValueError("❌ REDIS_URL required in production")
CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': REDIS_URL,
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',
        },
        'TIMEOUT': 300,
    }
}

# --------------------------------------------------
# 🔴 Runtime Redis Health Check (IMPORTANT)
# --------------------------------------------------
if REDIS_REQUIRED and not DEBUG:
    try:
        from django_redis import get_redis_connection
        conn = get_redis_connection("default")
        conn.ping()
    except Exception as e:
        raise Exception(f"❌ Redis not reachable: {e}")

---

Axes Protection

MIDDLEWARE += [
    'axes.middleware.AxesMiddleware',
]

# --------------------------------------------------
# 🔐 AXES HARDENING (ALIGNED)
# --------------------------------------------------
# Axes fallback behavior
# False = Fail Closed (secure) | app becomes unusable if Redis is down → recommended for maximum security in production
# True = Fail Open (usable) | app continues but reduced security (no rate limiting, no lockouts) → use only if you have a reliable Redis connection in production
AXES_FAIL_SILENTLY = True if DEBUG else False
# AXES_ENABLED = True
AXES_ENABLED = True if REDIS_REQUIRED else DEBUG
AXES_VERBOSE = True # (optional) Log lockouts with more detail (check logs → you’ll see exactly why login fails)
AXES_CACHE = 'default'
AXES_FAILURE_LIMIT = 5
AXES_COOLOFF_TIME = 30
AXES_RESET_ON_SUCCESS = True
AXES_USERNAME_FORM_FIELD = 'email'
AXES_LOCKOUT_PARAMETERS = ['username', 'ip_address']
# Optional UI override
AXES_LOCKOUT_TEMPLATE = 'sauth/lockout.html'

Email Settings

# --------------------------------------------------
# 📧 EMAIL CONFIGURATION
# --------------------------------------------------
EMAIL_BACKEND = (
    'django.core.mail.backends.console.EmailBackend'
    if DEBUG else
    'django.core.mail.backends.smtp.EmailBackend'
)

EMAIL_HOST = os.getenv("EMAIL_HOST")

if not DEBUG and not EMAIL_HOST:
    raise ValueError("❌ EMAIL_HOST must be set in production")

EMAIL_PORT = int(os.getenv("EMAIL_PORT", 587))
EMAIL_USE_TLS = os.getenv("EMAIL_USE_TLS", "True").lower() == "true"
EMAIL_HOST_USER = os.getenv("EMAIL_USER")
EMAIL_HOST_PASSWORD = os.getenv("EMAIL_PASS")
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

Logging settings (extend existing logging)

# --------------------------------------------------
# 🧾 LOGGING (EXTENDED FOR SAUTH)
# --------------------------------------------------
LOGGING['loggers'].update({
    'sauth.audit': {
        'handlers': ['console', 'security_file'],
        'level': 'INFO',
        'propagate': False,
    },
    'sauth.app': {
        'handlers': ['console', 'app_file'],
        'level': 'INFO',
        'propagate': False,
    },
    'sauth.ratelimit': {
        'handlers': ['console', 'security_file'],
        'level': 'WARNING',
        'propagate': False,
    },
})

---

🧠 Role-Based Redirection (already in #3 Required Settings)

SAUTH = {
    "ROLES": {
        "admin": "/dashboard/admin/",
        "staff": "/dashboard/staff/",
        "user": "/dashboard/",
    }
}

---

📧 Email Integration

• you can use in your project the email sending function using:

from django_sauth.core.flows.email_flow import send_general_email

send_general_email(
    request,
    user,
    "Welcome!",
    "emails/welcome.html",
    {"name": user.first_name}
)

create the templates/emails/welcome.html

---

🧾 Audit Logging

• to use the audit log feature inside your project:

from django_sauth.security.audit.logger import log_event

log_event(request, "login_success", user=request.user)

log_event(
    request=None,
    event="manual_test_error",
    level="error",
    extra={"info": "testing"}
)
