SecAppDev 2023 workshop details

Designing and building secure user authentication mechanisms

Learning goal: In-depth understanding of the security properties provided by modern authentication mechanisms, along with the technical knowledge to implement these mechanisms in modern web applications.

Thursday June 15th, 09:00 - 17:30
Room West Wing

User authentication is a critical component in almost every application. In this workshop, we explore user authentication and investigate which mechanisms are available in modern applications, along with their security properties, pros, and cons. You will learn about state-of-the-art passwordless authentication mechanisms, including the Web Authentication API and the newly-introduced PassKey mechanism. Additionally, we explore multi-factor authentication mechanisms and their security properties.

This workshop consists of a mix between lectures, demos, interactive quizzes, and hands-on labs.
