A Passwordless Future! Passkeys for Java Developers
Weak passwords remain one of the major causes of breaches and security incidents. The Web Authentication standard provides a robust framework for passwordless authentication using passkeys. Passkeys are the latest revolution in authentication. You may have used it with Google or GitHub. But what exactly is it and how does it work? You will learn all about it in this talk.

We will dive into the core concepts of passkeys, their architecture, and their pros and cons. We will see how Passkey leverages public key cryptography and biometrics/hardware authenticators to offer enhanced security and usability while eliminating the vulnerabilities associated with traditional password-based systems.

We will explore how Java developers can leverage WebAuthn Java libraries to implement passkeys in their apps. We will also learn to use passkeys with Spring Security and external Identity providers. There will be demos, showing step-by-step integration of passkeys into Java web applications.

A Design Pattern goes to the Supermarket
Everybody knows the term design patterns. Some know the patterns and correct implementation by heart. Others vaguely recognize the pattern names but don’t recall the details. This talk is intended for the latter group.
I’ll dive into a couple of design patterns using real-life examples. What would a design pattern look like in day-to-day life? We’ll follow Bobby and Billie and discover how a design pattern would behave in a non-digital environment: the supermarket! With the help of drawings and code snippets, this talk will give you a solid understanding of design patterns, so you won't have to look them up ever again!
