Multichannel User Authentication: Telnyx Verify API
Today we’re excited to announce the general availability of Telnyx’s multichannel Two-Factor Authentication solution, Verify.
Telnyx customers can now perform two-factor authentication (2FA) on an expanded range of customer-preferred channels, including WhatsApp, push notification, flash calling, and more.

Naturalizing 2FA

Two-factor authentication (2FA) is a staple for account and platform security. From online banking and transactions to new account creations to mere account sign-ins, requiring a secondary form of identity verification at critical points in user journeys has become standard practice.
The 2FA processes we’ve come to know achieve this verification through one of three avenues: something you know, something you have, or something you are. Phones (something you have) are today’s ubiquitous 2FA device, with SMS dominating delivery of one-time passwords (OTPs).
At Telnyx, we’ve seen a clear need for a more versatile 2FA solution—one that enables one-time password delivery via the channels most native to your specific user journey. Whether you need push notifications within an app onboarding, flash calling in regions with poor SMS delivery rates, or email for desktop-based transactions, Telnyx’s Verify API offers the channels that make your customer experience most cohesive.

Simplifying the build

With Telnyx, multichannel 2FA is as basic or configurable as your needs require. Our award-winning Mission Control Portal offers ready-to-use code per channel integration—enabling you to authenticate users via SMS, WhatsApp, Voice, flash call, RCS, email, push notification, or even cellular data in no time. Meanwhile, our extensive documentation and 24/7 in-house engineering support are always on hand for more complex configurations.
For industries that require higher levels of compliance, Telnyx is here to help. Verify enables you to become PSD2-compliant at the click of a button, with pre-built code available to help your platform meet all PSD2 requirements.
The Verify API offers more 2FA channels than any other CPaaS provider today, and it’s built on the industry’s only cloud-agnostic IP network, which guarantees 99.999% uptime. Telnyx helps you deliver seamless and secure customer journeys at scale, wherever you’re going.
