SMS OTP Is Failing – Here’s What Comes Next, According to Vonage and AT&T

In this UC Today interview, host Kristian McCann sits down with Kunal Shukla, GM and Head of Network APIs at Vonage, and Chung H. Lee, AVP of Product Innovation at AT&T Business, to unpack why traditional authentication methods are breaking down—and what comes next.

From the hidden cost of fraud to the growing limitations of SMS-based verification, the discussion reveals why enterprises must rethink how they balance security with seamless user experiences. More importantly, it introduces a new, network-led approach that leverages telco intelligence to authenticate users silently—without adding friction.

This isn’t just theory. Vonage and AT&T break down how network APIs are transforming authentication and reducing friction across the customer journey.

Key points include:

Why a $10 trillion cybercrime economy is forcing businesses to rethink authentication strategies
How SMS OTP creates friction—and opens the door to phishing, interception, and poor UX
What “silent authentication” looks like using real-time network intelligence and telco data
How Vonage, AT&T, and partners are building an ecosystem to deliver secure, seamless digital trust
