✅ Login / Logout
✅ Forgot Password (secure token flow)
✅ Role-based redirects
✅ Tailwind / Bootstrap UI support
✅ Redis-backed rate limiting
✅ Axes brute-force protection
✅ Audit logging (SIEM-ready)

---

⚙️ Installation

pip install django-did-auth

---

🔧 Setup

1. Add to INSTALLED_APPS

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

---

2. URLs

Using full authentication:

• your_project/urls.py

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

    # DID_AUTH URLs
    path('auth/', include('django_did_auth.urls')), # Include DID_AUTH URLs

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

Or using only specific authentication:

• create urls.py at your app where custom_user model made
• Example: your_project/user_app/urls.py

from django.urls import path
from django.shortcuts import render
from django_did_auth.core.views.register import register_view
from django_did_auth.core.views.login import login_view
from django_did_auth.core.views.logout import logout_view
from django_did_auth.core.views.activation import activate_account_view
from django_did_auth.core.views.password_reset import (
    password_reset_request_view,
    password_reset_confirm_view
)

app_name = "did_auth"

urlpatterns = [
    # Authentication
    # path("register/", register_view, name="register"),
    path("login/", login_view, name="login"),
    path("logout/", logout_view, name="logout"),

    # Email Verification
    # path("activate/<uidb64>/<token>/", activate_account_view, name="activate"),
    # path("verification-sent/", lambda r: render(r, "did_auth/verification_sent.html"), name="verification_sent"),

    # Password Reset
    # path("password-reset/", password_reset_request_view, name="password_reset_request"),
    # path("password-reset-confirm/<uidb64>/<token>/", password_reset_confirm_view, name="password_reset_confirm"),
]

then include it on url project urls

• • your_project/urls.py

from django.contrib import admin
from django.urls import include, path

from core_system import settings

urlpatterns = [
    path('admin/', admin.site.urls),
    path('auth/', include('user_app.urls')), # from `your_project/user_app/urls.py`
]

IMPORTANT: for disabling / or using specific authentication, use custom Templates (see below)

---

3. Required Settings

AUTH_USER_MODEL = 'users.CustomUser'

# Admin security
MIDDLEWARE.insert(0, 'django_did_auth.security.admin.ipwhitelist.AdminIPWhitelistMiddleware')

• Default DID_AUTH config (can be overridden in dev/prod):

🔐 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',

    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 = 'did_auth/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 DID_AUTH)
# --------------------------------------------------
LOGGING['loggers'].update({
    'did_auth.audit': {
        'handlers': ['console', 'security_file'],
        'level': 'INFO',
        'propagate': False,
    },
    'did_auth.app': {
        'handlers': ['console', 'app_file'],
        'level': 'INFO',
        'propagate': False,
    },

        'handlers': ['console', 'security_file'],
        'level': 'WARNING',
        'propagate': False,
    },
})

---

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

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

---

📧 Email Integration

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

from django_did_auth.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_did_auth.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"}
)
