In the Quarkus Security framework, identity providers play a key role in authentication and authorization, providing services for storing and verifying user identities.
The Jakarta Persistence IdentityProvider creates a SecurityIdentity instance used during user authentication to verify and authorize access requests, making your Quarkus application secure.
IdentityProvider converts the authentication credentials provided by HttpAuthenticationMechanism to a SecurityIdentity instance.
Some extensions, for example, OIDC, OAuth2, and SmallRye JWT have inline IdentityProvider implementations specific to the supported authentication flow.
For example, quarkus-oidc uses its own IdentityProvider to convert a token to a SecurityIdentity instance.
If you use Basic or form-based authentication, you must add an IdentityProvider instance that can convert a username and password to a SecurityIdentity instance.
To get started with security in Quarkus, we recommend you combine the Quarkus built-in Basic HTTP authentication with the Jakarta Persistence identity provider to enable role-based access control (RBAC).
