Overview

The T2F2-NFC-Slim is the Token2 take on a smaller NFC enabled key. While they also have the T2F2-NFC, that key has a large thumbdrive style form factor. The key is about as slim as the TrusKey models, but not as thin as YubiKey, presumably related to the style of manufacturing – plastic clamshell vs injection molded. The key stands out with some graphics printed on the matte case, and it feels lighter than it may look. There is a capacitive touch sensor on the outer edge next to the keychain hole. There also is a white LED status light on that end of the key.

Available Features And Management

The T2F2-NFC-Slim supports FIDO2 as well as FIDO U2F and with the associated companion software, HOTP and TOTP.

FIPS 140 Availability

Token2 does not produce a FIPS 140 variation of this key.

Enrollment And Usage

The key enrolled in Azure AD without issue.

The key worked consistently as a USB security key. On the NFC side, I was finding the key to be a bit particular in usage. The key would only seem to consistently work when placed on the NFC reader with the USB contacts face down; face up it would seem to struggle to stay connected, even with trying to adjust the placement. Considering I’ve had no issues with other NFC devices, I’m not sure if my test key is just an odd-one out or if there is a design flaw here.

The key was factory reset without issue.
