Passwordless in Production: Implementing FIDO Passkeys for Frontend

In this session, I'll share our end-to-end journey implementing FIDO passkeys in our frontend, replacing traditional password authentication with a more secure, frictionless solution. I'll dive into our technical architecture, frontend integration challenges, cross-platform considerations, and critical UX decisions that balanced security with user experience. You'll discover how we tackled browser compatibility issues, optimized performance, and overcame unexpected hurdles during our production rollout. Drawing from our real-world implementation serving millions of users, this talk provides actionable insights for developers considering or currently implementing passwordless authentication, complete with code examples, lessons learned, and tangible results that demonstrate the impact of our transition to passkeys.
