T2F2-NFC-Slim is an NFC-enabled FIDO2 Security key. 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. T2F2-NFC-Slim model features a capacitive sensor-type integrated touch-button. T2F2-NFC is only 6 mm thick.

FIDO  security keys are small USB dongles that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards. 

Token2 T2F2-NFC-Slim  security key combines hardware-based authentication, public-key cryptography, TOTP/HOTP, U2F, and FIDO2 protocols to protect your accounts. This type of security devices provides the highest level of multifactor authentication of user accounts with Twitter, Facebook, Gmail, GitHub, Dropbox, Dashlane, Salesforce, Duo, Centrify and hundreds more HOTP, U2F, and FIDO2 compatible services. No additional tools or applications are required, and the login process is simple and reliable. Just insert the Security Key into a USB-A slot and authenticate with a simple touch. We also sell a compact USB-A to Type-C adapter, so you can use the same key with devices with USB-Type-C slots. The T2F2-NFC-Slim security key does not require a battery nor network connectivity - it is always on and accessible.

NFC Chip position

The NFC chip is located on the front/top side of the device (the USB metal connectors' side). While for good quality NFC reader devices (i.e. an iPhone), both sides would work with no issues, on devices with weaker NFC signal, touching the reader area with the top side of the key would give better results.

TOTP Feature
T2F2-NFC-Slim Security key can securely store the secrets for your TOTP profiles, but requires a companion app (available for Android and Windows) to generate the OTPs.
