We’re back with another part of the series Conquer Authentication with KtoRemember where we left off in Part 6? We learned how to implement authentication with JWT but that lingering question remained: What happens once the access token expires? Today, we will address this concern and learn how to easily refresh an expired token in the background, without asking the user to re-authenticate.
Welcome back to our journey with the Ktor framework. Our previous post introduced you to JSON Web Tokens (JWT) and their impact on authentication in modern web applications. You learned about the key benefits of JWT, such as statelessness, improved scalability, cross-platform compatibility, and enhanced security. Today, we take things a step further with a hands-on approach, showing you how to effectively implement JWT using Ktor. Follow along as we dive into the practical side of JWT with Ktor to secure your web application seamlessly and effectively. By the end of this post, you’ll have a deeper understanding of how JWT and Ktor work together to create a robust and maintainable security model.
Welcome back to our ongoing series on the Ktor framework and its impressive capabilities when it comes to web application security. In this article, we shift our focus from traditional form-based authentication to a modern, innovative one – JSON Web Tokens (JWT). JWT provides several key advantages that have led to its growing popularity. Firstly, its stateless nature promotes better scalability by eliminating the need to maintain user sessions. Secondly, JWT’s JSON structure guarantees cross-platform compatibility. This means your authentication mechanism works equally well for web apps as it does for mobile apps or other systems. Lastly, JWT proactively increases the security of your applications, preventing attacks like CSRF. So, join us today as we delve into the world of JWT, exploring its mechanics and benefits.
Welcome to the continued exploration of form-based authentication with Ktor. Today’s post delves into session management—a feature that enables the persistence of user data across multiple HTTP requests. Session management allows users to securely access protected resources after initial authentication. Once the user logs in, the server persists user data and automatically re-authenticates users on subsequent requests. This is not only convenient from a user’s perspective but also reduces the risk of credential interception, a vulnerability inherent in basic authentication.
Welcome to the latest instalment in our series on implementing authentication with Ktor. In the previous post, we delved into the intricacies of basic authentication. Today, we’re enhancing our security measures by addressing one notable drawback — the need to pass user credentials with each request. By the end of this post, you’ll understand the workings of form-based authentication and why it’s a superior choice over basic authentication.
Welcome to the latest chapter in our ongoing series about implementing authentication with Ktor. Having laid a solid foundation by covering the fundamentals of Ktor, we’re now prepared to delve into the realm of security protocols. In today’s post, we’re going to start with the simplest one – Basic Authentication. We’ll unpack how this protocol functions and guide you through its implementation using Ktor.
