Consumer IAM (CIAM) & Personalization at Scale

How does ACP manage the transition from a federated IT service provider to a secure and efficient CIAM solution? In this presentation, you will learn how ACP uses Single Sign-On (SSO) not only to strengthen security but also to improve the user experience and simplify identity management. Gain practical insights into the transformation toward a future-proof solution for modern enterprises.

Managing digital identities at scale is a major challenge for telecommunications providers. Large customer bases, increasing security threats, strict regulatory requirements, and complex multi-brand environments create significant pressure on identity systems.

In this session, Bare.ID and congstar share how they modernized their CIAM landscape to support more than 7 million customer identities across multiple brands. Instead of treating security and user experience as trade-offs, they established both as key guiding principles to create a reliable, user-centric login experience. A key part of this journey was the shift to passwordless login using Passkeys – turning secure login into an almost invisible experience while significantly strengthening protection behind the scenes.

The session highlights the real-world challenges behind this transformation: balancing consistent identity management with independent brand experiences, reducing operational complexity, and meeting regulatory requirements such as GDPR and NIS2.

Attendees will gain practical insights into how large organizations can simplify authentication, drive passwordless adoption, and build a scalable identity platform that earns customer trust throughout the entire authentication process.
