1. Authentication & Access Control
Multi-Factor Authentication (MFA) Setup
Facebook Business Account MFA:
- 1Go to Facebook Business Settings → Security → Two-Factor Authentication
- 2Choose authenticator app over SMS (SMS can be intercepted)
- 3Add backup codes and store them securely
- 4Enable login alerts for unknown devices
Platform Account Security (OnSync):
- 1Enable SSO (Single Sign-On) if available
- 2Use unique, strong passwords (20+ characters)
- 3Set up session timeouts and idle logout
- 4Monitor login activity and unusual access
🔒 Security Impact:
Implementing MFA reduces account compromise risk by 99.9%. Businesses with MFA experience 95% fewer security incidents.
Role-Based Access Control (RBAC)
| Role | Permissions | Use Case | Security Level |
|---|---|---|---|
| Admin | Full system access, user management, security settings | IT managers, business owners | Critical |
| Manager | Team management, analytics, reporting | Team leads, supervisors | High |
| Agent | Message conversations, customer profiles | Customer service reps | Medium |
| Viewer | Read-only access to conversations and reports | Analysts, auditors | Low |
2. API Security & Token Management
Secure Token Storage & Rotation
✅ Best Practices:
- • Use environment variables, never hardcode tokens
- • Store tokens in secure vaults (AWS Secrets Manager, Azure Key Vault)
- • Rotate tokens every 90 days automatically
- • Use different tokens for dev/staging/production
- • Implement token expiry monitoring
- • Log token usage and access attempts
❌ Avoid These Mistakes:
- • Storing tokens in code repositories
- • Using same token across all environments
- • Never rotating tokens
- • Sharing tokens via email or chat
- • Using tokens with overly broad permissions
- • Ignoring token expiry warnings
🔄 OnSync Token Rotation:
OnSync automatically rotates your WhatsApp API tokens every 60 days and provides 30-day expiry warnings. No manual intervention required.
Webhook Security & Signature Verification
⚠️ Critical: 43% of WhatsApp Business breaches in 2024 involved compromised webhooks. Always verify webhook signatures.
Webhook Signature Verification (Essential):
// Node.js example
const crypto = require('crypto');
function verifyWebhookSignature(payload, signature, secret) {
const expectedSignature = crypto
.createHmac('sha256', secret)
.update(payload, 'utf8')
.digest('hex');
return crypto.timingSafeEqual(
Buffer.from(signature, 'hex'),
Buffer.from(expectedSignature, 'hex')
);
}
// Reject invalid signatures
if (!verifyWebhookSignature(body, signature, webhookSecret)) {
return res.status(401).send('Invalid signature');
}Additional Security Measures:
- • Use HTTPS-only webhook endpoints
- • Implement rate limiting (100 req/min)
- • Validate all incoming data
- • Log all webhook requests
- • Use IP whitelisting for webhook sources
