Authenticating users can start simple with a username and a password for each user. But you will also need to handle forgotten passwords and user registration. You might also want to validate email addresses, add second factors and have users update their profile information as needed. A single-sign-on system like Keycloak can handle all that for you and will redirect users after they are authenticated to your applications. See how you can delegate authentication by leveraging features of OpenID Connect. We will start simple and enable more and more features in our demo to show the functionality and flexibility of Keycloak. We will also look at features of the latest release and the road map ahead.
