An affordable security key combining FIDO, NFC, USB, and OTP support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
The FEITIAN ePass FIDO-NFC Security Key is a hardware authentication key for individuals and organizations securing web accounts, legacy OTP workflows, and passwordless sign-in. The K9B and K40 variants combine NFC and USB connectivity, with USB-A on one model and USB-C on the other. Authentication support covers FIDO U2F, FIDO2, HOTP, and TOTP, making the key relevant to buyers who want one device for modern phishing-resistant authentication and established OTP methods.
Platform coverage is broad for a hardware key: the product supports Windows, macOS, Linux, iOS, Android, and Chrome OS. USB operation follows the standard USB HID model without a driver, while NFC enables contactless authentication on compatible mobile devices. The secure element and JavaCard operating system provide protected credential storage, and support for multiple account credentials helps the key serve more than one login. A vendor app is specified for device management, while the key itself is not open source.
Pricing is straightforward according to the vendor's category page: the ePass FIDO-NFC Security Key K9B/K40 costs $35 as a one-time purchase. That single plan includes NFC and USB connectivity, FIDO U2F and FIDO2, plus HOTP and TOTP. Buyers should choose it when affordable NFC access, USB authentication, and OTP support matter more than biometric unlocking. It is also a practical fit for mixed desktop and mobile environments, provided the selected connector matches the devices in use. Buyers seeking built-in biometric unlock should consider a different security key.
