Case Study: Babylon Health achieves HIPAA-compliant, scalable login for 300,000 users and saves a year of development time with Auth0

Why Babylon Health Relies on Auth0 to Scale Globally

Babylon Health, a UK digital healthcare leader that connects patients and clinicians remotely and partners with organizations like the NHS, faced a growing authentication challenge: its bespoke, hard-to-maintain login system couldn’t scale to support partner integrations, social logins, and strict regulatory requirements (including HIPAA). The team needed a secure, convenient solution that would handle diverse user types and let them onboard partners quickly without diverting engineering resources.

After a build‑vs‑buy evaluation Babylon selected Auth0, implementing both user and machine‑to‑machine authentication. The move enabled HIPAA‑compliant access, streamlined partner integrations, and now supports about 300,000 active users; it also saved roughly a year of development time for an eight‑person team and reduced costs with pay‑per‑active‑user pricing, freeing engineers to focus on Babylon‑specific product work.
