How 2 Factor OTP Works

Intercept the login

A user logging into an account first confirms their username and password, but to be certain that the user is who they say they are, our Verify API gets involved.

Our Verify API reaches out

We send a one-time access code — via SMS, voice, or push notification — to the phone associated with that username and password.

The account owner confirms

When the code arrives on the phone user associated with the account, the owner keys in the short verification code into the input box presented by the app.

Comprehensive solution

We invent the Verify API to make it simple to implement. Your application simply gives us a phone number and we take care of the rest. We’ve got you enclosed for SMS, voice, and SMS to voice fail-over scenarios. We even make sure the messages comply with local coordination so they are not filtered by the carriers. Our comprehensive back end provides the security code and identity management capabilities, all behind a simple to use API.

Highest deliverability

Our many direct-to-carrier relationships around the world, combined with our proprietary Adaptive Routing algorithm, allow us to work in real-time to find the best routes for your messages. Add that to our Compliance Engine, which knows how and when to deliver messages according to country and carrier requirements, and you have the industry’s highest deliver ability rates.
