Why Authgear

The complete solution that scales with you

Not just cheaper OTPs: a full identity platform that cuts costs while improving security and UX.

Immediate Cost Reduction of Up to 90%
WhatsApp OTP with automatic SMS fallback. WhatsApp costs a fraction of SMS. Users with WhatsApp get their code there. Everyone else gets SMS. No friction, instant savings.
Costs Shrink Every Month with Biometrics
Mobile biometric login and passkeys mean returning users authenticate with face or fingerprint. No OTP sent. The longer your users stay, the fewer OTPs you send.
No Surprise Fraud Bills
SMS pumping attacks can generate thousands of fraudulent OTPs overnight. Authgear's device fingerprinting and risk-scoring block them before they hit your bill.
Single Sign-On Across Your Apps
Users log in once and stay logged in across all your properties. Launch companion apps without login friction. One identity, one consent, one customer view.
Enterprise-Grade Security Out of the Box
User audit logs, account lockout, rate limiting, breach detection, and OWASP best practices, already built and maintained by us. Your team ships features instead.
Works in 219 Countries
WhatsApp has 2+ billion users globally. 215 of 219 markets show savings, from 33% in Germany to 94% in Egypt and 93% in Nigeria. Your global expansion doesn't have to cost more.

The Problem

Your current options fall short

SMS OTP is a tax on growth. Every new user costs you money.
The obvious fixes don't actually solve it.

Build In-House
Full control, but expensive engineering time and ongoing maintenance. Biometrics and passkeys are hard to build right, and the spec keeps changing.
Costly & slow
Switch to a Cheaper SMS Gateway
Simple swap of API keys, but you still pay per OTP. Costs still scale linearly with users. No fraud protection, and cheaper gateways often have worse delivery rates.
Still scales with growth
Add a Security Product
Bot and fraud protection, but high cost, separate from auth, and more integration work. Often overkill for SMS abuse specifically.
High cost, more complexity
