WeRoad, a European adventure travel company, faced authentication challenges as it rapidly expanded. The DevOps team needed a single sign-on solution that worked across multiple applications, supported social login, mobile app authentication, machine-to-machine authentication, passwordless options, and maintained data sovereignty for GDPR compliance. After evaluating several authentication solutions, WeRoad selected FusionAuth due to its cost-effective scaling, self-hosting capability, simplified deployment, comprehensive feature set, and customization options. Since implementing FusionAuth in 2021, WeRoad has experienced substantial cost savings, enhanced data control, easy maintenance, scalable authentication, and seamless integration into their infrastructure-as-code practices.
