La clase SecurityTokenProvider es responsable de obtener los tokens para un ServiceModelSecurityTokenRequirement determinado. Opcionalmente, los proveedores de token pueden permitir la renovación y también la cancelación de los tokens. El proveedor de token puede almacenar en memoria caché los tokens si se configura para ello.
