T2F2-NFC-Dual is an NFC enabled security key with 2 USB ports: USB-A and USB Type-C. Having an NFC chip onboard allows using this FIDO2 key with modern iPhones natively, directly in the browser (starting from iOS 13.3) as well as Android devices with NFC. Dual USB port design allows using the same key with computers having USB-A and USB-TypeC ports without the need of carrying and using adapters.
FIDO security keys are small USB dongles that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards.

Metallic cases of T2F2-NFC-Dual can potentially interfere with the NFC signal of the device, causing it to be blocked. This happens because metal acts as a barrier to the transmission of electromagnetic waves, including the NFC signal. To avoid this issue, it is important to unfold the metal casing before using NFC, or use the plastic version
of this device.
