django-phone-verify 3.3.0

What It Does

django-phone-verify handles the complete phone verification flow:

1. Send Verification Code - User requests verification, receives SMS with security code

2. Verify Code - User submits code, system validates and confirms phone number

3. Session Management - Secure JWT-based session tokens prevent tampering

4. Multiple Use Cases - Registration, 2FA, password reset, marketing opt-in, and more

Key Features

Security & Flexibility

• 🔐 Secure verification flow - JWT session tokens, configurable code expiration, one-time use options

• 🔧 Highly customizable - Token length, expiration time, message templates, custom backends

• 🔒 Production-ready - Rate limiting support, security best practices, GDPR/CCPA compliance guidance

Easy Integration

• 🚀 Django REST Framework - Pre-built viewsets and serializers for instant API setup

• 🔌 Pluggable backends - Use Twilio, Nexmo/Vonage, or write your own (AWS SNS, MessageBird, etc.)

    },
    "TOKEN_LENGTH": 6,
    "MESSAGE": "Welcome to {app}! Please use security code {security_code} to proceed.",
    "APP_NAME": "Phone Verify",
    "SECURITY_CODE_EXPIRATION_SECONDS": 3600,  # in seconds
    "VERIFY_SECURITY_CODE_ONLY_ONCE": False,
}

For Nexmo (Vonage):

PHONE_VERIFICATION = {
    "BACKEND": "phone_verify.backends.nexmo.NexmoBackend",
    "OPTIONS": {
        "KEY": "your-nexmo-api-key",
        "SECRET": "your-nexmo-api-secret",
        "FROM": "YourApp",  # Sender ID
        "SANDBOX_TOKEN": "123456",  # Optional: for testing
    },
    "TOKEN_LENGTH": 6,
    "MESSAGE": "Welcome to {app}! Please use security code {security_code} to proceed.",
    "APP_NAME": "Phone Verify",
    "SECURITY_CODE_EXPIRATION_SECONDS": 3600,
    "VERIFY_SECURITY_CODE_ONLY_ONCE": False,
}

Quick Start

Step 1: Send verification code

curl -X POST http://localhost:8000/api/phone/register/ \
  -H "Content-Type: application/json" \
  -d '{"phone_number": "+1234567890"}'

# Response:
# {
#   "session_token": "eyJ0eXAiOiJKV1QiLCJhbGc...",
#   "phone_number": "+1234567890"
# }

Step 2: Verify the code

curl -X POST http://localhost:8000/api/phone/verify/ \
  -H "Content-Type: application/json" \
  -d '{
    "phone_number": "+1234567890",
    "security_code": "123456",
    "session_token": "eyJ0eXAiOiJKV1QiLCJhbGc..."
  }'

# Response:
# {
#   "message": "Security code is valid",
#   "phone_number": "+1234567890"
# }

Using in Python/Django code:

from phone_verify.services import send_security_code_and_generate_session_token
from phone_verify.services import verify_security_code

# Send verification code via SMS
session_token = send_security_code_and_generate_session_token(
    phone_number="+1234567890"
)
# User receives SMS: "Welcome to Phone Verify! Please use security code 847291 to proceed."

# Verify the code user entered
try:
    verify_security_code(
        phone_number="+1234567890",
        security_code="847291",
        session_token=session_token
    )
    print("✓ Phone number verified successfully!")
except Exception as e:
    print(f"✗ Verification failed: {e}")
