What is FIDO2?

What is FIDO2?

U2F was developed and contributed to the FIDO Alliance after it was successfully deployed for Google employees. The protocol is designed to act as a second factor to strengthen existing username/password-based login flows.

FIDO2 is an internationally developed technology standard

Passwords - A Growing Security Risk

Passwords - A Growing Security Risk

Passwords are weak, often reused, and easily forgotten — making them prime targets for phishing and brute-force attacks. For enterprises and government systems, this means higher IT costs, compliance gaps, and a frustrating user experience.

How It Works:
Inside the FIDO2 Architecture

Supported Configurations

1 Token + Button

  • Simple presence verification: press to confirm login or approve actions.
  • Ideal for SSO, quick logins, and basic step-up authentication.

2 Token + PIN

  • Adds device-bound PIN for stronger access control.
  • Suited for enterprise workstations and internal systems.

3 Token + PIN + Biometric

  • Highest security level: combines physical presence, PIN, and biometric verification (fingerprint or facial recognition, model-dependent).
  • Designed for critical systems, regulated industries, and Zero Trust deployments.

Cryptographic Security Model

  • Per-service key pairs — unique keys generated and stored in the token for each service.
  • Private key isolation — the private key never leaves the device and is inaccessible to host or cloud.
  • Origin binding — authentication requests are tied to the correct domain, preventing spoofing and MITM attacks.
  • Tamper-resistant storage — secure element (SE) protects keys from extraction, malware, and physical compromise.

Security benefit:

Even if a client device or network is compromised, Synera F2 authentication cannot be replayed or hijacked.

Core Protocols

  • WebAuthn — a browser/server API enabling passwordless login in web applications. Supported by all major browsers and operating systems.
  • CTAP2 (Client to Authenticator Protocol v2) — enables secure communication between the token and the host device (laptop, phone, workstation), confirming user presence and intent.

Why it matters:

Together, these protocols create a login flow that never transmits or stores passwords, OTPs, or other shared secrets — making it inherently phishing-resistant.

Frequently Asked QuestionsFAQ

Which token format is right for our organization?

It depends on how and where your users authenticate:

  • Nano / Micro form factors — best for laptops, travel, or embedded use
  • USB-A / USB-C keys — ideal for desktops, workstations, and shared terminals
  • Biometric tokens — recommended for high-assurance environments, such as critical infrastructure, secure facilities, and executive access

We can assist in selecting the optimal format based on your infrastructure, policy, and threat model.

Is Synera F2 compatible with iOS and Android?

Yes. Synera tokens work natively on iPhone and Android devices via WebAuthn-capable browsers and operating systems. No extra drivers or apps needed. Plug-and-play login for mobile banking, email, and eGov services.

Can a single token be used across multiple services?

Yes. Each Synera token generates unique, isolated credentials per service, ensuring:

  • No credential reuse across platforms
  • One device for both internal (SSO, VPN) and external (banking, identity, email) access
What happens if a token is lost?

For individuals

  • PIN and biometric protection prevent unauthorized use
  • Backup login or re-registration can be enabled (if configured in advance)

For organizations:

  • Centralized lifecycle control allows revocation, replacement provisioning, and audit logging
  • Full traceability supports compliance and incident response
Is Synera F2 compliant with cybersecurity and regulatory frameworks?

Yes. Synera F2 is built on internationally recognized open standards, including:

  • FIDO2, WebAuthn, CTAP2
  • Aligned with Zero Trust Architecture (ZTA) and NIST SP 800-63B
  • Compatible with eIDAS, GDPR, and national ID systems (where applicable)
