Authentication is a foundational requirement for most web applications, but, in order for it to work, we need a way to pass user data securely – for example, from our front-end web application to our backend API. The JWT (which stands for JSON Web Token) specification was created for exactly this purpose. In this session, Dan Moore will show you what JWTs are, how they work and everything you need to know to use them properly in your applications.

What Developers Need to Know About JWTs

What is a JSON Web Token (JWT) and why do you care? JWTs are a stateless, standardized way to represent user data. This talk will discuss why JWTs matter and the nuts and bolts of JWTs. We’ll also discuss how you might use a JWT in your applications and how to avoid common mistakes.
