You can feel secure that the YubiKey 5Ci USB-C and Lightning Security Key protects your device. Finally, there’s a hardware-backed authentication device for your iPhone. While this security key works with both USB-C and Lightning connections, there hasn’t previously been much available for Apple devices. Additionally, this USB-C security key works on both mobile and desktop devices. Because of this feature, you need to carry only this authentication key rather than multiple hardware security keys. Additionally, it has a hole that easily fits on a keyring, so you have a simple way to keep it with your everyday carry items. Furthermore, this key works with a variety of services and iOS apps. So whichever encryption and security service you prefer, you can probably use the YubiKey 5Ci with it.
