Introduction
FIDO replaces the shared-secret model that every legacy authentication system inherits. Instead of storing passwords or one-time-password seeds in a central database, FIDO binds credentials to hardware that signs challenges directly — leaving nothing useful for an attacker to phish or exfiltrate. Traditional authentication systems store confidential information centrally, creating vulnerability. "FIDO is already one of the pillars of web security of many international companies."
FIDO enables phishing-resistant authentication through public-key encryption without requiring users to share physical devices. It reduces password fatigue while maintaining strong security across multiple services without linking accounts.
FIDO U2F, FIDO2 and FIDO Resident credentials
Three authentication approaches:
- U2F — second-factor authentication with physical keys
- FIDO2 — passwordless authentication
- FIDO Resident Credentials — username-less login
Benefits of FIDO
- Strong Security — Physical MFA resistant to interception, phishing, session hijacking, and MITM attacks. Lost tokens contain no identifying information.
- Secure Recovery — Users register multiple devices; providers offer backup codes.
- Easy to Use — Native browser support (Firefox, Safari, Chrome, Edge, Opera). Hardware-based authentication requires no driver installation or code entry. Single tokens support multiple sites.
- Strong Privacy Protections — Users control identity presentation. Unique key pairs generated per service prevent cross-provider secret sharing.
- Interoperability — Supported by major internet and financial firms.
- Flexibility in Choice — Works with various authentication modalities.
Conclusion
The OnePass USB Key implements FIDO2 to help organizations transition toward password-less authentication, reducing security risks while improving user experience. The technology requires no battery or network connectivity.
