Authentication is a critical part of any modern web application, ensuring that users can securely access resources while preventing unauthorized access. This course provides a comprehensive guide to authentication in Node.js, covering essential and advanced authentication techniques used in real-world applications.

You will learn how to implement secure authentication systems using JWT (JSON Web Token), OAuth2, SSO (Single Sign-On), API keys, and session-based authentication. The course focuses on best security practices, including password hashing, token expiration management, multi-factor authentication (MFA), and role-based access control (RBAC).

By the end of this course, you will have the skills to build and deploy a production-ready authentication system in Node.js using popular authentication strategies.

Authentication Methods You Will Learn

• Session-based authentication (stateful, using cookies and sessions)

This course is designed to equip you with in-depth knowledge of authentication in NestJS, covering both fundamental concepts and advanced security techniques. By the end of the course, you will have the skills to build scalable, secure authentication systems for real-world applications.

By the end of the course, you will have built a complete authentication system that is scalable, secure, and production-ready.
