## Description

<<< UPDATE 4.1 >>>
- background.js & content.js para poner el código automáticamente sin dar click

Da mucha pereza tener que estar cogiendo el móvil y viendo el código de 6 dígitos para entrar en los servicios de la US o en su defecto copiarlo desde una extensión, ¿no?. Bien pues esta extensión hace el proceso un poco más ligero, ya que te genera el código TOTP para el SSO directamente en tu navegador.
