Token2 PIN+ Dual Ace R3.4 - NFC FIDO2.1 Security Key with Metal Frame
The PIN+ Dual Ace is an NFC-enabled FIDO2 Security key with both USB-A and USB-TypeC ports, featuring PIN complexity at the firmware level. Unlike the standard PIN+ Dual, the Ace model features a metallic zinc alloy frame for superior durability and a premium feel, with front and back panels made of polycarbonate to ensure unobstructed NFC signal transmission. Having an NFC chip onboard allows using this FIDO2 key with modern smartphones natively. This model features two capacitive sensor-type touch buttons, located on the front and back panels. With Release 3.4 of our PIN+ Series you can also add an optional OTP protection.
Firmware 3.4 Release
Version 3.4 builds on the functionality introduced in Release 3.3 and adds the following enhancements:
- Enhanced PIV security and protocol support.
- Secure Messaging (SM): Added encrypted communication support.
- Advanced OTP Security: Password-protected OTPs with a security lockout after 100 failed attempts and a 5-minute authenticated session for OTP operations.
- Optimized Stability: Improved USB-C compatibility for certain devices and added high-voltage protection for secure use with docking stations.
FIDO security keys are small USB dongles that enable secure login to websites and applications supporting FIDO2 WebAuthn and classic FIDO (U2F) standards.
PIN+ security key combines hardware-based authentication, public-key cryptography, TOTP/HOTP, U2F, and FIDO2 protocols to protect your accounts. This type of security device provides the highest level of multifactor authentication for 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 slot and authenticate with a simple touch. The security key does not require a battery nor network connectivity - it is always on and accessible.
Durable Metal Construction
The Ace model features a metallic zinc alloy frame, providing enhanced protection against impacts, bending, and everyday wear compared to plastic-bodied keys. The polycarbonate front and back panels are precision-engineered to allow the NFC antenna to operate without interference, while the PCB retains a specialized protective coating for enhanced water resistance.TOTP Feature
PIN+ Security key can securely store the secrets for your TOTP profiles but requires a companion app (available for Android, iPhone, and Windows, as well as a cross-platform Python tool allowing it to run under Linux, macOS, and similar systems) to generate the OTPs. With Release 3.4, OTP profiles can additionally be protected with a password: after 100 failed authentication attempts the OTP function is locked out, and a successful authentication opens a 5-minute session for OTP operations.
