PIN+ Release3.3 USB-A - FIDO2, U2F, PIV and TOTP Security Key with PIN complexity feature (T2F2-NFC-Slim)
The PIN+ Release3.3 USB-A is a FIDO2 Security Key featuring a classic USB-A connector and advanced PIN complexity enforcement at the firmware level. Designed for desktops, laptops, and enterprise environments, this model delivers robust, hardware-based authentication in a compact and durable form factor. It includes a capacitive sensor–type integrated touch button and a slim profile for everyday use.
Firmware 3.3 Release
Version 3.3 introduces PIV functionality alongside the existing feature set, expanding the key’s capabilities for smart card–based authentication and enterprise identity workflows.
FIDO Security Keys
FIDO security keys are small USB devices that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards. With the PIN+ Series, you can store up to 300 passkeys (also known as resident keys or discoverable credentials) on a single device.
The PIN+ Release3.3 USB-A combines hardware-based authentication, public-key cryptography, TOTP/HOTP, U2F, and FIDO2 protocols to protect your accounts. It provides a high level of multifactor authentication for platforms such as Twitter, Facebook, Gmail, GitHub, Dropbox, Dashlane, Salesforce, Duo, Centrify, and hundreds of other HOTP, U2F, and FIDO2-compatible services. No additional software is required—simply insert the security key into a USB-A port and authenticate with a touch. The key requires no battery and no network connectivity; it is always ready for use.
