FIDO2-Certified BLE Dongle
A Bluetooth Low Energy dongle enabling FIDO2 password-less authentication with enterprise-grade security. Built on a low-power Nordic nRF microcontroller, the device replaces password-based login for web and desktop services with strong, phishing-resistant cryptographic authentication — certified by the FIDO Alliance.

2023The Challenge
Traditional password-based authentication systems are fundamentally vulnerable: users choose weak or reused passwords, phishing attacks routinely steal credentials, and centralized password storage creates high-value breach targets. Achieving both strong security and everyday convenience seemed mutually exclusive — until hardware authentication keys changed the equation.
Our Solution
We developed a FIDO2-certified BLE dongle that implements the complete FIDO2/WebAuthn standard on a Nordic nRF microcontroller. The device performs cryptographic challenge–response authentication over Bluetooth Low Energy, eliminating stored credentials entirely. Private keys never leave the hardware; only public keys are registered with services. Certification by the FIDO Alliance confirms interoperability with all compliant platforms and guarantees adherence to the highest authentication standards.
Key Features
- FIDO2 / WebAuthn compliant: Full implementation of the FIDO2 standard for phishing-resistant, password-less login on web and desktop platforms.
- FIDO Alliance certified: Officially approved for compliance, security, and interoperability with all FIDO2-supporting services and browsers.
- BLE low-power connectivity: Bluetooth Low Energy pairing with mobile and desktop devices for convenient, cable-free authentication.
- Hardware-isolated key storage: Private keys generated and stored on-device with hardware-level isolation — never exposed to the host system.
- Robust cryptography: ECC P-256 key pairs, encrypted handshake, and secure key management protect every authentication event.
- Ultra-low-power design: nRF architecture maximizes battery life for portable, everyday-carry use without compromising security.
