Passwordless Authentication

Introduction As organizations and developers continue shifting toward passwordless authentication, two standards often come up: FIDO and FIDO2. While closely related, these standards represent different stages in the evolution of secure, phishing-resistant login technology. This article explains the technical and strategic differences between FIDO (U2F) and FIDO2, their roles in modern authentication, and how to choose the right standard for your app or enterprise environment. What Is FIDO? FIDO (Fast IDentity Online) originally referred to a family of open standards developed by the FIDO Alliance to improve authentication security through: ...

Introduction Password-based authentication has long been the weakest link in application security. With phishing, credential stuffing, and password reuse rampant, modern organizations are looking toward passwordless authentication methods that are more secure and user-friendly. This post explains how to use a YubiKey hardware security key to implement FIDO2-based passwordless login using WebAuthn, including optional integration with enterprise IAM solutions like ForgeRock Identity Cloud. What Is FIDO2 and Why YubiKey? FIDO2 is an open standard for passwordless authentication, co-developed by the FIDO Alliance and the World Wide Web Consortium (W3C). It combines two components: ...

Introduction Traditional login systems—relying on passwords and MFA tokens—are increasingly vulnerable to phishing, credential stuffing, and human error. In contrast, FIDO login offers a modern, passwordless alternative built on public key cryptography, ensuring a seamless yet secure user experience. This blog post explores the technical implementation and benefits of FIDO login for modern applications, whether you’re building from scratch or integrating into an existing IAM system like ForgeRock, Okta, or Azure AD. ...

In an era where digital identities are increasingly valuable, traditional password-based authentication is proving to be a liability. Password fatigue, phishing attacks, and credential stuffing are just a few of the challenges that have pushed organizations to seek more secure and user-friendly alternatives. Enter passwordless authentication—a paradigm shift in how we verify identities. This blog post explores the current state, benefits, challenges, and future trends of passwordless authentication, backed by real-world examples and technical insights. ...
