Problem Statement
As a platform powering digital coaching businesses for thousands of educators, Classplus manages millions of user interactions each month. But behind the scenes, its reliance on traditional OTP-based authentication was starting to strain both operations and the user experience.
The challenges were twofold:
Rising authentication costs that scaled rapidly with every new user onboarded.
Inconsistent OTP delivery from third-party providers, leading to login delays, failures, and frustrated users.
Adding to the complexity, the Classplus team was eager to offer WhatsApp-based authentication to improve reliability and user satisfaction. However, building and maintaining that flow in-house—especially at Classplus’s scale—posed a significant engineering challenge.
It was clear that Classplus needed a smarter, more cost-effective authentication system that could deliver seamless access without overloading their tech teams or budget.

Integrating WhatsApp login at scale is no small feat. From managing templates and session logic to orchestrating APIs and fallback flows, the process demands significant engineering investment—especially for a platform the size of Classplus.
That’s where OTPless came in.
