How It Works

Seamless authentication in four simple steps

1

User Initiates Login

The merchant or app redirects the user to OTPless via a lightweight SDK or API integration.

2

Smart Auth Routing

OTPless dynamically chooses the best authentication channel based on device type, carrier, region, and past success data.

3

Instant Verification

User's identity is verified silently in the background or via WhatsApp confirmation, with no manual input required.

4

Secure Token Return

OTPless returns a verified identity token (JWT/opaque token) to the merchant, completing authentication in under 3 seconds.

Multiple Channels

Authentication Channels

Multiple secure, frictionless verification methods

WhatsApp Login

Tap to verify identity securely through official WhatsApp APIs. Instant and familiar.

Silent Mobile Verification

Authenticate mobile numbers in the background using telecom signals — no user action needed.

Passkeys

FIDO2-based passwordless authentication for future-ready, secure login experiences.

Smart Fallback OTP

Intelligent fallback when required, managed via OTPless routing engine for reliability.
