Case Study: BT Group achieves secure multi-brand customer authentication with Kocho and Azure AD B2C

BT Group onboards 5 million customers with Kocho

BT Group, a multinational telecommunications company with brands including EE and Plusnet, faced the challenge of creating a secure, seamless authentication experience across its multiple brands and services. They partnered with Kocho and adopted Microsoft Azure AD B2C to build a Single Authentication Framework (SAF) to replace a time-consuming process where users had to register for each service separately.

Kocho implemented Azure AD B2C to provide a single, secure 'front door' for authentication across all brands. The solution successfully migrated millions of customer accounts with no disruption. Results for BT Group included onboarding 5 million customers within weeks, thwarting over 100,000 attacks, a sharp drop in customer abandonments, and the ability to process over 1 million IDs in just 4 minutes during a major event. Kocho's expertise was crucial in delivering this scalable and secure platform.
