public class ValidateWebAuthnAssertion
extends AbstractAuditingValidationAction

An action that validates a WebAuthn authenticator assertion that results from a call to WebAuthn's 'get' credential API. If successful, populates the Subject with a UsernamePrincipal based on the username in the authentication context and a WebAuthnUserIdPrinicpal based on the user.id in the authentication context.

Event:

AuthnEventIds.INVALID_CREDENTIALS, AuthnEventIds.INVALID_AUTHN_CTX
