Presentations

A session at Identiverse 2025 which explores the nuanced dynamics between passkeys and verifiable digital credentials, and their technological foundations across usability, privacy, trust models, and ecosystems with the goal of answering whether passkeys and verifiable digital credentials are friends or foes—and how these technologies might collaboratively shape the future of secure, user-centric digital identity systems.

This talk at Internet2 TechEx 2024 centered on passkeys: their arrival in 2022, how they work, their impact on security and user experience, and what the future holds with federation and digital identity wallets.

a session at Authenticate 2024 which dives into the intricate relationships between websites, browsers, apps, operating systems, passkey providers, and security keys, and each party’s role and impact on user experience and functionality.

Topics # At TPAC 2023, we introduced the topic of digital identity wallets and their use on the web, and asked the community for use cases, concerns, and asked browser engine maintainers to express interest in this work.
