Easy Session Sharing in Spring Boot with Spring Session and MySQL
Session management in multi-node applications presents multiple challenges. When the architecture includes a load balancer, client requests might be routed to different servers each time, and the HTTP session might be lost. In this tutorial, I’ll walk you through the configuration of session sharing in a multi-node Spring Boot application. Prerequisites: Java 8+ Docker Docker Compose Table of Contents Session Persistence Session Sharing with Spring Session Learn More about Spring Session and OAuth 2.0 Session...
How to Build Securely with Blazor WebAssembly (WASM)
Last month I came out with a video tutorial on Blazor WebAssembly and I thought it would be good to follow up with a written tutorial as well. Youtube Link Because of the JS Interop, Blazor WASM has some key differences in the world of OAuth. Instead of thinking of this as a normal .NET back end application, you have to think of what Blazor resolves to in the browser - and that’s Javascript. Therefore,...
How to Adapt Your .NET App for SameSite
Have you run across an error message vaguely referencing SameSite in your .NET Apps? Read on, it’s time for a change to your code - and I’ll explain why. I like cookies, both the custard stuffed and the dry ones (which I use to dunk in my coffee or tea). This post is very much about cookies - only not the delicious, culinary ones. As in many other cases (think of the web, for example),...
Easy Authentication for Ruby On Rails Login
A couple of things have changed in the Rails world since we published our last blog post on Rails. For one, Rails 6.0 was released on August 16, 2019 (Yay progress!), and, for another, Omniauth had a CRSF vulnerability reported (not so great). Does this make you a bit anxious? Don’t worry! Today we will be going over how to create a Rails app from scratch with the new Rails release and go over how...
How to Secure PII with Entity Framework Core
When the products we develop collect sensitive data, it’s essential to secure and safeguard it to protect user privacy and the user’s identity. Personally identifiable information (PII) is any data that can be used to identify a specific individual, such as name, email address, phone number, US Social Security number, birth date, and so on. Yet companies also need to store user-related data that is not as sensitive as PII. In this tutorial, you will...
Reintroducing Joël Franusic
Hi, my name is Joël Franusic and I’m happy to announce that I am, once again, a developer advocate at Okta, focusing on the Python and Go communities. (Why do I say “once again”? Because six years ago, I started my Okta career as a developer advocate but over the course of time I worked in a series of other roles including: “Software Engineer”, “Technical Marketing Manager”, and “Product Marketing Manager”) This blog post has...
Ionic + Sign in with Apple and Google
Apple announced a Sign in with Apple service at its WWDC developer conference in June 2019. If you’re familiar with social login with Google or Facebook, it’s very similar. Most of these identity services use OAuth and OpenID Connect (OIDC), and Apple’s implementation is similar. Today I’d like to show you how to develop a mobile application with Ionic, add OIDC authentication, retrieve the user’s information, and add social login (aka federated identity) with Apple...
Migrate User Passwords with Okta's Password Hook
Okta is an identity platform focused on making authentication easy to build with minimal code. Our goal at Okta is to build a solution so flexible and easy to use, that you’ll never have to build authentication again. And while Okta can provide a lot of new functionality to your application, including multi-factor authentication (MFA) based on contextual policies, self-service password resets, and federation to enterprise identity providers and social media accounts, we’ve found that...
Build a React App with ANT Design Principles
For years the go-to HTML/CSS framework of choice for developers was Bootstrap. A new contender has appeared in the form of Ant Design. Ant should feel familiar to veteran developers but it’s built on new principles. Their site spends a good amount of effort distinguishing between good and bad design. There is an emphasis on clarity and meaning. Ant Design is heavily based on psychological principles to anticipate—and be customized for—user behavior. Ant Design is...
Build Your First Deno App with Authentication
The creator of Node.js, Ryan Dahl, has authored a new framework for designing web applications. He went back and fixed some mistakes he made in hindsight, taking advantage of new technologies that were not available at the time he originally wrote Node. The result is Deno (pronounced DEH-no), a framework for writing “Node-like” web applications in TypeScript. Here, I will walk you through creating a basic web application with authentication. You can find almost all...
