Security Key NFC

The Security Key NFC provides the FIDO2 application as well as the U2F application, and can communicate using near-field communication (NFC), allowing for greater flexibility.

Interface

The Security Key NFC uses a USB 2.0 interface as well as an NFC interface. All of the applications are available through both interfaces.

Applications

U2F

The U2F application can hold an unlimited number of U2F credentials and is FIDO certified.

FIDO2

The FIDO2 application allows for secure 1FA and 2FA authentication and can store credentials, allowing for username-less login. Up to 25 resident credentials can be stored, with up to 3 of the credentials being RSA. The credentials on this application can be PIN protected for extra security.
