Yubico YubiKey 5Ci - Two Factor Authentication Android/PC/iPhone Security Key, Dual Connectors for Lighting/USB-C - FIDO Certified USB Password Key, Protect Online Accounts with More Than a Password

This product does not seem to work. It is a total waste of money. I got it refunded.

I am very pleased with the Yubico YubiKey 5Ci. Shipping was prompt, and the security key arrived well-packaged and protected, with no signs of damage. The dual-connector design—featuring both USB-C and Lightning plugs—was exactly as advertised and ready for immediate setup. In terms of product quality, this YubiKey feels solid and reliable. The build quality gives confidence that it will withstand daily carry on a keychain, and the connectors seat securely into devices without wiggle or looseness. Setting it up with my accounts was straightforward; the configuration steps were clear and compatible with the MFA options in most services I use. Functionally, the key enhances security through hardware-based authentication rather than relying solely on passwords or SMS codes. It supports modern authentication standards such as FIDO2/WebAuthn and U2F, providing a practical second factor for logging into email, cloud services, password managers, and other online accounts that support security keys. The dual Lightning and USB-C connectors make it especially useful for iPhone users and other Apple devices that lack conventional USB ports. Yubico +1 From a value perspective, this security key offers strong protection at a reasonable cost compared with subscription-based alternatives or more complex enterprise solutions. Its broad platform compatibility—covering iOS, macOS, Windows, Linux, and many web services—adds versatility. While not every app supports hardware keys yet, the ecosystem continues to expand, and the YubiKey remains a robust, future-oriented investment in account security. Overall, this is a well-made, dependable MFA solution that combines convenience with significant security benefits, and I would confidently recommend it.

حلووو كتيرررر .. شكررراً كتيرررر ..

It is my first time using. Yubico key but the configuration is simple and it works with all platform’s that require multi factor authentication. It works for apple devices and usb c devices it’s small which is great for keeping with you on a keychain but I would suggest getting 2 in case one gets lost. Great product.{edited}

Parfait comme clé pour la sécurisation à double facteurs d’authentification. Utilisée pour comptes GMAIL, APPLE…parfaitement reconnue sur les iPhone que ce soit avec prise USB ou Lightning.

Artículo de gran calidad y funcionamiento muy sencillo, idóneo para la seguridad en el pc o el móvil.
