In this lightning talk we will dive into the emerging world of Passkeys – a revolutionary approach to authentication that promises to reshape our digital security landscape. We'll explore the fundamental workings of Passkeys: their underlying technology, how they differ from passwords, and their reliance on public key cryptography. The session aims to prepare the AmsterdamJS community for this upcoming shift in authentication paradigms, equipping developers with the knowledge to embrace and implement Passkeys in their future projects. Join me in this exploration of Passkeys, as we step into a new era of digital security and user authentication.
