Enterprise & Service Use Cases
What is the FIDO NFC Plus USB-A K9D used for?
The FIDO NFC Plus USB-A K9D is a hardware security key used for strong, phishing-resistant authentication in enterprise and service environments. It supports FIDO2 and FIDO U2F standards, enabling passwordless login and secure two-factor authentication for users and organizations.
How does the FIDO NFC Plus USB-A K9D help prevent phishing and Man-In-The-Middle attacks?
The security key uses hardware-based cryptographic authentication instead of shared secrets or passwords. Authentication credentials never leave the device, which prevents phishing, credential replay, and Man-In-The-Middle (MitM) attacks commonly associated with password-based systems.
Does the ePass FIDO-NFC Plus Security Key K9D support both desktop and mobile use?
Yes. The device features dual USB-A and NFC interfaces, allowing secure authentication on desktop and laptop systems via USB-A, and tap-based authentication on NFC-enabled mobile devices and access systems.
Which authentication protocols are supported?
In addition to FIDO2 and FIDO U2F, the K9D supports OTP (HOTP/TOTP), PIV, and OpenPGP. This multi-protocol support allows enterprises to use a single authenticator for modern passwordless login, smart card authentication, VPN access, email encryption, and legacy systems.
Is the FIDO NFC Plus USB-A K9D compatible with multiple operating systems?
Yes. The device works with FIDO-compliant applications on Windows, macOS, and Linux, ensuring consistent authentication across diverse enterprise environments.
Why should enterprises use a hardware security key instead of passwords?
Hardware security keys significantly reduce the risk of account compromise, lower helpdesk costs related to password resets, improve user experience, and support compliance with modern security frameworks. They offer stronger protection than passwords while simplifying authentication workflows.
