Secure OAuth 2.0 Access Tokens with Proofs of Possession
In OAuth, a valid access token grants the caller access to resources and the ability to perform actions on the resources. This means the access token is powerful and dangerous if it falls into malicious hands. The traditional bearer token scheme means the token grants anyone who possesses it access. A new OAuth 2.0 extension specification, Demonstrating Proof of Possession (DPoP), defines a standard way that binds the access token to the OAuth client sending...
How Authentication and Authorization Work for SPAs
Adding authentication to public clients such as Single Page Applications (SPA) and JavaScript applications can be a source of confusion. Identity Providers like Okta try to help you via multiple support systems. Still, it can feel like a lot of work. Especially since you’re responsible for way more than authentication alone in the applications you work on! As part of authentication, your client application makes multiple calls to an authorization server, and you get back...

Build a CRUD App with Vue.js, Spring Boot, and Kotlin
Much like React or Angular, Vue.js is a JavaScript view library. When coupled with a state management library like MobX, Vue.js becomes a full-featured application framework. Vue.js is designed to be incrementally adoptable, so you can use as much or as little of it as you like. Like React, Vue.js utilizes a virtual DOM to streamline processing so that it renders as little as possible on each state update. In my experience, Vue is far...

Use Vue and GraphQL to Build a Secure App
When you develop a new web application, you most likely split the application into two parts. The server-side provides access control and data persistence, while the client-side is mostly presentational. The two parts have to communicate, and your first idea may be to implement a REST API. However, a number of flaws have been identified with the RESTful pattern, mostly related to the flexibility and speed of the request-response pattern. At Facebook, these problems were...
