Security & Data Privacy.
Built from the ground up for high compliance, strict data isolation, and tamper-proof authentication. Here is how we safeguard every verification attempt.
100% Indian Data Residency
All FlashAuth services, message queues, and verification databases are hosted exclusively in AWS Mumbai (ap-south-1). No phone numbers or authentication tokens ever leave Indian borders.
Salted SHA-256 Zero-Knowledge
We never store raw plaintext OTPs in our persistent databases. Verification codes are immediately hashed using salted SHA-256 and retained in ephemeral memory with an automatic 5-minute TTL.
Anti-SMS Pumping & Fraud Defense
Automated IP geo-fencing, burner phone filtering, and exponential backoff rate limits protect your wallet from malicious bots and SMS pumping attacks.
CERT-In & DPDP Compliance
Our infrastructure strictly complies with the Indian Computer Emergency Response Team (CERT-In) logging guidelines and Digital Personal Data Protection Act (DPDPA) standards.
TLS 1.3 & Encrypted Transit
All HTTP payloads and carrier webhooks are strictly encrypted in transit via TLS 1.3 with AES-256-GCM cipher suites and perfect forward secrecy.
Isolated Project Sandboxing
Each project environment maintains isolated API keys, segregated rate limits, and cryptographic salt generation to prevent cross-application data leakage.
Zero-Knowledge Cryptographic Safeguards
FlashAuth complies with strict data governance guidelines. All verification codes are immediately hashed using salted SHA-256 and retained exclusively in ephemeral memory with automated 5-minute time-to-live expiration.
