FIDO2

FIDO2 is the latest evolution in the realm of passwordless authentication, building upon the foundations laid by FIDO (Fast IDentity Online). As an IAM engineer, understanding the differences and advancements between FIDO and FIDO2 is crucial for implementing robust, secure authentication systems. What is FIDO? FIDO is a set of open standards for authentication that aims to replace passwords with more secure methods. The FIDO Alliance, a global industry association, developed these standards to enhance online security by reducing reliance on passwords, which are often weak and easily compromised. ...

Passkeys are a modern approach to authentication that leverages FIDO2 WebAuthn standards to provide secure, passwordless login experiences. By using public key cryptography and biometric verification, passkeys offer a robust alternative to traditional passwords, enhancing both security and user convenience. What is FIDO2 WebAuthn? FIDO2 WebAuthn is a standard for strong, passwordless authentication that uses public key cryptography. It allows users to authenticate to online services using biometrics (like fingerprints or facial recognition), security keys, or built-in authenticators (such as TPM chips). The WebAuthn API provides a way for websites to interact with these authenticators, enabling secure and seamless authentication processes. ...

In early March 2026, two events put MFA bypass back in the spotlight. Europol dismantled Tycoon 2FA — the world’s largest phishing-as-a-service platform — while a new suite called Starkiller demonstrated that AitM phishing has evolved from a sophisticated nation-state technique into a commodity SaaS product anyone can buy. The message is clear: if your organization relies on TOTP, push notifications, or SMS for MFA, it is not phishing-resistant. Here’s how these attacks work and what actually stops them. ...

Unlike traditional methods that rely on shared secrets (e.g., passwords or OTPs), FIDO2 uses public key cryptography with hardware-backed credentials to provide strong, phishing-resistant authentication. ...
