Technical Guide
OTP and Verification
We handle the complexity of generating, sending, and expiring one-time passwords for you. You just tell us where to send it.
Client-Ready (Instant)
Connect directly from your web or mobile app without a backend. Great for quick user verification and newsletter signups.
The workflow is simple: Send -> Receive -> Verify. We handle the tokens and security gates for you.
Secure-First (Backend)
For higher security actions like payments or password resets. This mode gives you full control over code length (4-8 digits) and expiration times.
Built-in Security
We automatically block brute-force attempts. If someone gets the code wrong multiple times, we instantly invalidate it and throttle the attacker's IP to keep your users safe.
