WhatsApp OTP Security Architecture
  • Cryptographic Hashing: Raw 6-digit OTPs are never stored in plaintext. The database retains only sha256(otp + '_OICAFE_SALT_2026').
  • Cooldown & Rate Limiting: Enforces 60-second cooldown per mobile and max 15 requests/hour to prevent WhatsApp API quota exhaustion.
  • Brute-Force Protection: Maximum 5 incorrect verification attempts before the code is permanently invalidated.
  • Auto Guest Cart Migration: Upon successful OTP verification, guest shopping bags are merged automatically into the customer's permanent user record.
