Case Study: Coop achieves 25x traffic scalability with Auth0's automated identity

How Coop Automated Identity to Handle 25x More Traffic

Coop Norge, Norway’s second-largest consumer-owned retailer with about 1.9 million members, faced a legacy on‑prem identity system that was hard to scale and caused performance bottlenecks during peak events (traffic spikes up to 25x). Their old setup relied on token validation for up to 85% of traffic, and they needed a cloud-based, elastic identity solution that could secure both customer-facing and backend services without disrupting users.

Coop migrated incrementally to Auth0, routing clients through custom connections so they could move one client at a time with no downtime, and automated tenant and configuration management via the Auth0 Management API and Terraform for “zero‑click” ops. The change enabled fast MFA rollout (BankID in a day), seamless user experiences during complex backend reengineering, scalable handling of peak traffic, reduced manual ops, and strong vendor support throughout the project.
