• Quarkus Authentication

Quarkus supports different authentication mechanisms through different extensions. For example:

• quarkus-elytron-security-properties-file provides support for simple properties files that can be used for testing security. This supports both embedding user information in application.properties and standalone properties files.

• quarkus-security-jpa provides support for authenticating via JPA.

• quarkus-elytron-security-jdbc provides support for authenticating with JDBC

• quarkus-smallrye-jwt provides support for authenticating using JSON Web Tokens. It allows you to inject the token and claims into the application as per the MicroProfile JWT specification.

• quarkus-oidc provides support for authentication via an OpenID Connect provider e.g. KeyCloak

• quarkus-keycloak-authorization provides support for a policy enforcer using Keycloak Authorization Services.
