Implementing OAuth2 and JWT

Moving on with the topic of application security, we will now discuss some of the more advanced mechanisms that cater to a changing environment. This brings us to two important technologies: OAuth2 and JWT.

In subsequent sections, we provide details of how to set up OAuth2 for Keycloak. We detail the configuration of OAuth2 for Keycloak, followed by the required code snippets. We will use Keycloak, an open source platform with full support for OAuth2 off-the-shelf protocols and extensive abilities to be customized, to provide Identity and Access Management (IAM).
