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

You will learn how to implementsecure authentication systemsusingJWT (JSON Web Token), OAuth2, SSO (Single Sign-On), API keys, and session-based authentication. The course focuses onbest security practices, includingpassword 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 aproduction-ready authentication systemin Node.js using popular authentication strategies.

Authentication Methods You Will Learn

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

JWT-based authentication(stateless, using access and refresh tokens)

OAuth2 & Social Login(Google, Facebook, GitHub, Okta)

Single Sign-On (SSO) with SAML & OpenID Connect

Two-Factor Authentication (2FA)for added security

API key authenticationfor secure service-to-service communication

Best practices for securing authentication endpoints

This course is designed to equip you within-depth knowledge of authentication in NestJS, covering bothfundamental conceptsandadvanced security techniques. By the end of the course, you will have the skills to buildscalable, secure authentication systemsfor real-world applications.

By the end of the course, you will havebuilt a complete authentication systemthat isscalable, secure, and production-ready.
