![]() Strong Authentication using Public Key Cryptography (which makes a credential)Ī specification developed by W3C and FIDO Alliance When built into browsers and platforms, it creates a private-public keypair (known as a credential), enabling passwordless authentication by connecting applications with strong biometric authenticators like Windows Hello or Apple’s Touch ID.īrowser API for Passwordless Authentication The WebAuthn API allows servers to register and authenticate users using public key cryptography instead of a password. The Web Authentication API (WebAuthn) is a specification developed by the World Wide Web Consortium (W3C) and the FIDO Alliance, with participation from an international array of major technology companies – including Cisco Security through Duo Security – actively contributing to WebAuthn development. ![]() In this article, we will go in-depth on the basic building blocks of passwordless technology: WebAuthn, FIDO, CTAP, FIDO2, and how it all comes together for the user. A current IT security trend, the password is replaced by much more secure factors in passwordless authentication, allowing for smoother usability without compromising on the additional benefits of having multiple factors. Passwordless authentication refers to a system that does not require the use of passwords at all. Experts in the fields of data protection and information security now look towards new technologies to make system access much more secure. While this isn’t entirely wrong, passwords are difficult to remember and rarely secure. After all, years of memorizing increasingly complex combinations of lower- and upper-case letters, numbers, and special characters have conditioned users to believe the fancier their password, the less likely they are to get breached. When someone is told that passwords are going away in favor of a new, “password-less” authentication method, a healthy dose of skepticism is not unwarranted. ![]() Industry News DecemJeff Yeo WebAuthn, Passwordless and FIDO2 Explained: Fundamental Components of a Passwordless Architecture
