Michael Schramm, CTO of Tucan.ai, discusses how his Berlin-based startup is using FusionAuth to enhance their authentication processes. Tucan.ai aims to improve meeting productivity through automatic transcripts and summaries, allowing participants to focus on conversations rather than note-taking. Facing challenges with user management, the team transitioned from using passport.js to FusionAuth, which offers better security and reduced maintenance needs. They have customized their authentication flows, such as implementing passwordless logins via SendGrid, while facing challenges with social logins due to incompatibilities with CockroachDB. FusionAuth is deployed on Kubernetes with CockroachDB for data storage, chosen for its failover capabilities and scalability. Schramm notes that using FusionAuth has saved time and increased security, though he highlights a desire for improvements in handling custom HTTPS headers for CDN compatibility.
