Introduction

In today's digital age, security is paramount. Two-factor authentication (2FA) adds an extra layer of security to your online accounts. This guide will walk you through the setup process of using Yubikey with Google, LinOTP, and Duo for secure OTP (One-Time Password) authentication.

Two-factor authentication requires two or more verification methods, typically something you know (like a password) and something you have (like a physical device or biometric identifier). This combination significantly reduces the risk of unauthorized access.
