In this presentation, I talk about OAuth and OIDC. I explain what they are, and how they work. Then I show a JHipster app that uses Keycloak and allows user registration. Next, I turn it into a PWA, and deploy it to Heroku. Along the way, I show how to switch to Okta. Then I show how Okta allows user registration, as well as UI customization.
