Implementing Passwordless Authentication for Modern Web Applications

Traditional passwords are a hassle for users to remember and a constant security risk for developers to protect. Transitioning to passwordless authentication streamlines the onboarding process while drastically reducing the risk of credential-based security breaches. This written guide teaches you how to design and implement modern, password-free login flows from scratch. You will start by learning foundational security terminology and the core mechanics of keyless verification. From there, you will explore how to implement and configure various modern authentication methods. By the end of this course, you will be prepared to deploy secure, friction-free authentication systems that your users will love. What you'll learn: - Understand the foundational concepts of passwordless authentication and modern security protocols. - Configure magic link email authentication flows for seamless user onboarding. - Implement one-time passwords (OTP) to verify user identity securely. - Explore modern WebAuthn standards and the integration of secure passkeys. - Apply industry best practices for user session management and secure token handling. - Design accessible, user-friendly login interfaces that eliminate credential fatigue. This course begins with essential definitions and architectural overviews before moving into clear, step-by-step written explanations and practical code examples. Designed specifically for beginner developers and security enthusiasts, this course requires no prior experience with advanced cryptography.
