One-Time Password Platform
High-reliability OTP generation and delivery platform supporting SMS, voice, and push-based one-time passwords for secure authentication.
The Authentication Crisis
Passwords alone are no longer security — they are a liability. OTP-based two-factor authentication is now mandatory for banking, payments, and enterprise access worldwide.
Password Breaches Cost Billions
Over 80% of hacking-related breaches involve compromised passwords. Static credentials are stolen, phished, and sold on the dark web every second. Without a second factor, every account is one password away from compromise.
SMS OTP Delays Kill Transactions
When an OTP takes 30+ seconds to arrive — or never arrives at all — customers abandon purchases, payments fail, and trust erodes. Every second of delivery delay costs real revenue in time-sensitive transactions.
Regulatory Non-Compliance Is Expensive
PSD2/SCA in Europe, RBI guidelines in India, PCI DSS globally — regulators now mandate multi-factor authentication for financial transactions. Non-compliance means fines, revoked licenses, and blocked market access.
How OTP Works
Four steps, under 2 seconds — from code generation to secure validation
Generate Secure Code
A cryptographically random 4-8 digit code is generated using TOTP (time-based) or HOTP (event-based) algorithms. Each code is unique, unpredictable, and single-use.
Deliver Instantly
The OTP is dispatched through the fastest available channel — SMS, voice call, push notification, or email — with automatic fallback if the primary channel is unavailable.
Validate in Real Time
When the user submits the code, the OTP platform validates it against the generated code within the validity window. Mismatch, expiration, or reuse is rejected instantly.
Expire Automatically
Every OTP has a configurable validity period — typically 30 to 300 seconds. Expired codes are purged. Each code can only be used once, preventing replay attacks.
Multi-Channel Delivery
OTP reaches users through four redundant channels — ensuring delivery even when one path fails
SMS Delivery
The most universal channel. Works on 100% of mobile phones globally. Optimized routing through direct SMSC integration for sub-2-second delivery in most markets.
Voice Call
Text-to-speech OTP delivery via automated phone call. Essential fallback when SMS is delayed or unavailable — particularly in roaming and cross-border scenarios.
Push Notification
Zero-cost delivery to smartphone users. OTP appears as a push notification — no need to switch apps or wait for SMS. Highest user experience with sub-second delivery.
Email Delivery
For web-based transactions and enterprise SSO scenarios. OTP delivered to registered email with HTML formatting and clear expiration instructions.
Security & Performance
Carrier-grade OTP platform meeting the most demanding security and throughput requirements
Five-nines uptime with geo-redundant active-active deployment. Zero downtime during maintenance. Every authentication request is processed — no dropped OTPs, no missed validations.
From generation request to OTP appearing on the user's phone in under 2 seconds. SLA-backed delivery guarantees for banking, payment, and enterprise authentication scenarios.
All OTP codes encrypted at rest and in transit. Cryptographic generation uses FIPS 140-2 validated modules. Tamper-proof audit logging for every generation and validation event.
Horizontally scalable architecture handles flash authentication peaks — Black Friday e-commerce surges, tax filing deadlines, and nationwide banking hours without throttling.

Real-Time Dashboard & Fraud Detection
Live monitoring of OTP generation rates, delivery success by channel, validation attempts, and geographic patterns. Anomaly detection alerts for brute-force attacks and unusual traffic patterns.
Frequently Asked Questions
What is the difference between TOTP and HOTP?
TOTP (Time-Based One-Time Password) generates codes that are valid for a specific time window — typically 30-60 seconds — based on the current time and a shared secret. HOTP (HMAC-Based One-Time Password) generates codes based on a counter that increments with each use. TOTP is more common for consumer applications because it doesn't require counter synchronization. ZBensoft OTP supports both standards, selectable per application.
How does OTP delivery work when SMS fails?
ZBensoft OTP platform implements multi-channel fallback with configurable priority. When the primary channel (e.g., SMS) fails or times out, the platform automatically retries on the secondary channel (e.g., voice call), then push notification, then email. Each fallback happens within milliseconds of the previous failure. The user experience is seamless — they simply receive the OTP through whichever channel works fastest.
Can the OTP platform integrate with existing identity systems?
Yes. ZBensoft OTP integrates with any identity provider or IAM system through standard protocols: OAuth 2.0, OpenID Connect, SAML 2.0, and LDAP. The platform can serve as the MFA layer for Microsoft AD, Okta, Auth0, Ping Identity, and custom authentication systems. RADIUS integration is available for VPN and network access authentication.
