A Passwordless Future! Passkeys for Java Developers by Deepu Sasidharan

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? Join me on an illustrated journey to learn everything about passkeys.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.
