Case Study: Bluetooth Special Interest Group achieves secure, standards-based SSO and granular access control with Auth0

How a standards-based organization implemented standards-based authentication via OpenID Connect and OAuth for improved security, access, and interoperability

Bluetooth Special Interest Group (SIG) is a not‑for‑profit standards organization that oversees Bluetooth technology for more than 34,000 member companies and roughly 150,000 users. Facing an aging homegrown authentication system, SIG needed a modern, standards‑based identity solution to deliver Single Sign‑On, enforce granular role‑based access across adopter/associate/promoter levels, and meet security and compliance needs without diverting scarce engineering resources to build and maintain a new platform.

SIG chose Auth0 to implement OpenID Connect and OAuth 2, integrating SSO, strong security practices, and its existing permissions model with minimal code changes and using the current user database. The rollout took days instead of months, improved security and attack mitigation, provided a cost‑effective active‑user licensing model, preserved access controls, and freed engineers to focus on core projects while enabling future enhancements like MFA and API protection.
