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.
What is FIDO2?
FIDO2 is the second generation of FIDO standards, focusing on providing a seamless and secure passwordless authentication experience. It introduces WebAuthn (Web Authentication), a browser-based API that allows websites to use public key cryptography for user verification. This means users can authenticate themselves using biometric data, security keys, or other hardware tokens, eliminating the need for traditional passwords.
