2026-06-19 , A218 (capacity 20)

Have you ever heard about passkeys or WebAuthn?
Yes? Great than this workshop is for deepening your knowledge!
Or
No? Great than this workshop is for building up your knowledge!

We will be building a simple application (Web or mobile, you choose) that signs up and logs a user into a web service using Passkeys (either physical or virtual).

BUT that's not all: After the user flow is established, we'll also highlight some special extensions, useful for extended use of your Passkeys. Think about encrypting data with one of them.

Let's deep dive into the magic of cryptography with passkeys and each other.


Experience level: Intermediate - attendees should be familiar with the subject

Maker of things: Technologically (Software, Hardware), DIY (3d printing, sewing, crafting), Engaging Content (GDG Berlin Android, speaker at several conferences and Meetups worldwide)

Let's talk about anything and everything, except for my cats, they already have enough attention ... (JK, obiously we can talk cats too)
