Depois de uma semana, o token expirará e o usuário não estará autorizado, precisando fazer login novamente para obter um novo token. E se o usuário (ou uma terceira parte) tentar modificar o token para alterar a expiração, você seria capaz de descobrir isso, pois as assinaturas não iriam corresponder.

### Casos de uso: servicio externo

Un ejemplo podría ser que tienes un proveedor de autenticación externo al que necesitas llamar.

Le envías un token y te devuelve un usuario autenticado.

Este proveedor podría estar cobrándote por cada request, y llamarlo podría tomar más tiempo adicional que si tuvieras un usuario de prueba fijo para los tests.
