Theo Gravity, a senior engineer at Switchboard, discusses the company's use of FusionAuth to meet their authentication needs, highlighting its flexibility and extensive support for third-party identity providers. Switchboard, a collaborative digital workspace, transitioned from a password-based system to FusionAuth, appreciating its OAuth, custom JWTs, and passwordless authentication capabilities, which enhanced user experience and simplified account switching with Google. The team valued FusionAuth’s detailed documentation, intuitive SDKs, and community support, which facilitated a swift migration process completed in just four months. Theo emphasizes the platform's adaptability, allowing for customized authentication workflows, and praises its lambda support for adding custom logic. FusionAuth's ability to provide seamless calendar integration without additional sign-ins, and the option to self-host or use FusionAuth Cloud, were key factors in their choice, offering cost-effective solutions and reducing infrastructure maintenance needs.
