FEITIAN ePass FIDO-NFC Security Key

FEITIAN ePass FIDO-NFC Security Key is a hardware authenticator for FIDO sign-ins and HOTP/TOTP codes. It fits people who want one credential for desktop USB connections and NFC-enabled phones, with a choice of USB-A or USB-C. The $35 one-time purchase is attractive for broad account coverage, but buyers who require Bluetooth or biometric unlocking should choose another key.

Overview

The K9B and K40 combine FIDO U2F and FIDO2 authentication with OATH HOTP and TOTP one-time passwords. A single key can protect unlimited accounts across multiple websites, so it can consolidate security-key registrations and code-based authentication instead of requiring separate devices for each service.

FEITIAN builds the key around a smart-card secure element and JavaCard operating system. Published cryptography includes ECDSA, SHA256, AES, HMAC and ECDH; FIDO U2F uses SHA256 with ECDSA on the P-256 curve. The K9 is FIDO U2F and FIDO2 certified, giving organizations recognizable standards for deployment and procurement.

Key features

• Four authentication methods: FIDO U2F and FIDO2 handle security-key and passkey-style authentication, while HOTP and TOTP provide one-time codes. That range suits mixed environments where some services support modern FIDO and others still require OTP.
• Two USB connector choices: K9B uses USB-A and K40 uses USB-C, so buyers can match the key to existing computers and hubs rather than relying on an adapter.
• NFC for mobile devices: Both models support NFC for registration and authentication on phones and other devices with an NFC sensor. This is useful when a mobile device has no convenient USB port.
• Driverless desktop operation: Windows, macOS and Linux recognize the key as a HID device over USB, avoiding a separate driver installation. It works with the latest Google Chrome and other FIDO-compliant applications; compatible services include Gmail, Facebook and Dropbox.
• Hardware-backed protection: The secure element and JavaCard foundation keep the credential in a dedicated device rather than on the host computer.
• No BLE or biometrics: The K9 feature set does not include Bluetooth Low Energy or biometric capability. That limits cable-free use away from NFC and means unlocking is not based on a fingerprint or other biometric.

Pricing

The ePass FIDO-NFC Security Key K9B/K40 costs $35, paid once (billed $35.00). It includes the choice of USB-A K9B or USB-C K40, NFC, FIDO U2F, FIDO2 and HOTP/TOTP. There is no free plan, subscription renewal or published usage quota: the purchase is for the physical key, and its account capacity is unlimited across websites.

FEITIAN also offers casing, printing, laser engraving and color customization. Organizations needing those options must request a quotation and detailed information, so custom work should be treated as custom pricing rather than part of the $35 standard purchase.

Platforms

The key supports Chrome OS, Windows, Linux, macOS, iOS and Android. USB HID operation covers Windows, macOS and Linux without drivers, while NFC extends registration and authentication to compatible mobile hardware. Browser use depends on Google Chrome or another FIDO-compliant application and service.

Who it's for

This is a strong fit for individuals and organizations protecting many accounts across desktop and mobile devices, especially in financial, healthcare, government, enterprise, payment and PSD2 settings. Choose the connector that matches your computers, then use NFC when mobile authentication is more convenient than plugging in. It is less suitable for deployments that demand Bluetooth proximity, biometric unlock or a management feature set beyond the key and its vendor app.

Pros and cons

Pros

• Broad authentication coverage: FIDO2, FIDO U2F, HOTP and TOTP support both newer and legacy sign-in requirements.
• Flexible hardware access: USB-A, USB-C and NFC cover common desktop and mobile connection patterns.
• Low ongoing cost: The $35 one-time price has no recurring plan, and one key can protect unlimited accounts.
• Standards-based security: FIDO certification, a smart-card secure element and documented algorithms give security teams concrete technical foundations.

Cons

• No wireless Bluetooth: Users without NFC who want cable-free authentication cannot use BLE with this key.
• No biometric unlock: Access does not include fingerprint or other biometric verification.
• Custom finishes require a quote: Branding and color work are not covered by the standard price.
