About
Astrotalk is India’s leading astrology and spiritual wellness platform, providing live consultations, personalized horoscopes, and services to over 50 million users globally. With 3+ million monthly logins, Astrotalk redefines digital astrology through a mobile-first, real-time experience. As the platform scaled across India and global markets, seamless and reliable authentication became critical.
Astrotalk relied on multiple SMS vendors and custom routing logic to manage authentication across regions—leading to:
~10% Drop-Off from OTP Failures impacting trust and topline
Manual Routing Logic increasing tech debt and ops overhead
Global Expansion Hurdles due to vendor-specific setups per country
The platform needed a unified, scalable authentication solution to eliminate friction and support international growth—without re-architecting.
OTPless replaced the fragmented OTP stack with a single, adaptive, and zero-touch authentication engine:
1. Silent Network Authentication (SNA)
Verified users silently over the mobile network—no OTPs, no clicks. Perfect for low-intent or poor-connectivity users, enabling seamless re-authentication and higher conversions.
2. WhatsApp & SMS Auto-Read
For WhatsApp-enabled users, OTPs were auto-read within the app—offering one-tap login experiences without redirect or manual entry. This boosted speed and convenience for a majority of users.
3. Smart Authentication Router
Delivered OTPs that were auto-read inside the app—eliminating user effort and reducing drop-offs from manual entry or app switching.
4. Unified Global Integration
A single SDK powered logins across India, US, Europe, UAE and new markets—without new setups or code changes.
🚀 Pilot Success
Within days, Astrotalk saw a 6–7% lift in login-to-subscription conversions and a sharp uptick in trust metrics.
