Case Study: BizReach achieves seamless migration of over 1 million users with Auth0

BizReach seamlessly migrates over 1 million users to Auth0

BizReach, a Tokyo-based HR tech company behind job search and talent platforms, needed to renew its authentication infrastructure for the B2C side of its business. The team wanted single sign-on across services, lower the cost and complexity of building authentication in-house, and better protect user data while migrating more than 1 million users without logging them out. To meet these goals, BizReach chose Auth0.

Auth0 provided migration capabilities, social login support, batch import tools, and APIs that let BizReach move active and inactive users in phases without disrupting access. The migration took about eight months with a three-person engineering team, and Auth0 helped BizReach complete it without logging out any users. The company also reported roughly a 50% reduction in implementation and operating costs compared with proprietary development, while freeing engineers to focus on core matching services.
