Learn about Whinself security features and best practices to protect your WhatsApp API integration.

Security Overview​

Whinself is designed with security in mind, providing a self-hosted solution that gives you complete control over your WhatsApp communication data. By hosting Whinself on your own infrastructure, you eliminate the risks associated with third-party API services handling your sensitive communications.

Security Features​

  • Self-hosted Architecture: All your data stays on your own servers, eliminating exposure to third-party services
  • Docker Isolation: Containerized deployment provides isolation from other applications
  • Access Control: Web interface protected by authentication
  • Secure WebSockets: Encrypted communication between components
  • End-to-End Encryption: Leverages WhatsApp's built-in end-to-end encryption for message content
  • Session Management: Secure handling of WhatsApp session credentials
  • QR Code Authentication: Secure pairing with WhatsApp via QR code scanning
  • Audit Logging: Comprehensive logging for security monitoring and troubleshooting

Authentication System​

Whinself implements a multi-layered authentication approach to protect your WhatsApp integration:

Web Interface Authentication​

The Whinself dashboard is protected by a user authentication system:

  • Email/Password Authentication: Secure login using email and password credentials
  • Session Management: HTTP-only cookies with secure flags for session maintenance
  • Account Verification: Email verification process for new account registration
  • Password Security: Passwords are securely hashed and never stored in plain text

WhatsApp Connection Authentication​

Connection to the WhatsApp network is secured through:

  • QR Code Authentication: Industry-standard WhatsApp QR code scanning process
  • Device Verification: WhatsApp's native device verification and registration
  • Session Persistence: Secure storage of WhatsApp session credentials
  • Automatic Reconnection: Secure session resumption without requiring re-authentication

API Access Security​

Protect your Whinself API endpoints using:

  • Network-level Controls: Deploy behind a firewall or in private networks
  • Reverse Proxy Authentication: Add authentication at the reverse proxy level (e.g., Nginx Basic Auth)
  • API Key Implementation: When using with API gateways, implement API key verification
  • IP Restrictions: Limit API access to trusted IP addresses
  • TLS Encryption: Always use HTTPS for all API communications

Security Integration Patterns​

For integrating Whinself with other systems, consider:

  • Webhook Signing: Implement webhook signature verification for incoming webhooks
  • Mutual TLS: Use client certificates for secure service-to-service communication
  • Zero Trust: Apply zero trust principles by verifying every access request

Security Best Practices​

Deployment Security​

  • Use Firewalls: Restrict access to your Whinself instance using network firewalls
  • HTTPS Implementation: Place Whinself behind a reverse proxy with HTTPS (e.g., Nginx with Let's Encrypt)
  • Private Networks: When possible, deploy Whinself on private networks not directly exposed to the internet
  • Regular Updates: Keep your Whinself container updated to the latest version

Configuration Security​

  • Secure Webhook URLs: Use HTTPS for webhook endpoints where Whinself sends notifications
  • Minimal Port Exposure: Only expose the necessary ports needed for operation
  • Environment Validation: Validate all webhook URLs and other external connections
  • Secure Configuration Storage: Protect your config.json file with appropriate file permissions

Operational Security​

  • Regular Backups: Maintain backups of your Whinself configuration
  • Monitor Logs: Regularly review logs for suspicious activities
  • Rate Limiting: Implement rate limiting on your application side to prevent abuse
  • Access Control: Restrict access to your Whinself administration interface
  • Session Management: Regularly refresh WhatsApp sessions when appropriate

Securing Your Application Integration​

When integrating your applications with Whinself:

  1. Authenticate API Calls: Implement authentication for calls to your Whinself instance
  2. Validate Input: Always validate and sanitize input data before processing
  3. Error Handling: Implement proper error handling to prevent information leakage
  4. Secure Storage: Securely store any sensitive data retrieved from Whinself
