Review: Cryptnox FIDO2 Security Key
Review: Llave FIDO2 fiable para reforzar el acceso sin contraseña - La he usado para iniciar sesión en varios servicios y la experiencia es sólida: la autenticación FIDO2 responde al instante y elimina la dependencia de contraseñas débiles o repetidas. El formato de tarjeta resulta cómodo de llevar y el NFC facilita el uso con móviles y portátiles sin puertos disponibles. También funciona por contacto, así que cubre bien distintos escenarios de acceso. La detección es estable y no he tenido fallos al registrar la llave en cuentas de Microsoft o Google. La construcción transmite buena durabilidad y el chip responde siempre a la primera. Para quien quiera añadir una capa real de seguridad sin complicar el flujo de trabajo, es una herramienta directa y eficaz.
