OTP & 2FA
Verification SMS

High-security one-time passcodes and two-factor authentication, delivered worldwide with end-to-end encryption and millisecond latency — so every login, payment and sign-up is protected.

How it works

Three steps to a verified user

1 · Trigger

Your app requests a code through our API when a user logs in, pays or signs up.

2 · Deliver

Horex routes the message over an optimized global network for fast delivery.

3 · Verify

The user enters the code; your system confirms it and completes the action.

FAQ

Questions

What is the difference between OTP and 2FA?

An OTP is a single-use passcode; 2FA uses that passcode as a second factor on top of a password.

How reliable is delivery?

Codes are sent over an optimized global network with real-time delivery-status tracking.

Can I integrate OTP with my existing system?

Yes — a REST API and multi-language SDKs connect to your app, CRM or website.

Is the delivery secure?

Verification traffic is protected with end-to-end encryption, aligned with international security standards.
