Authentication is an important part of web application security, but when it comes to securing single-page apps, it can often be confusing. How do you keep a user logged in? Where do you store tokens? How do you talk to APIs? In this session, we'll start with a blank React and Express application, install the Auth0 SDK, and secure our API calls. This is a 100% coding session, so bring your questions and we'll try to get through them all!
