Authentication and Authorization in Node.js

Understanding Authentication vs Authorization

Authentication verifies who a user is, while authorization determines what they can access. Both are crucial for secure applications.

JWT Implementation

JSON Web Tokens provide a stateless way to authenticate users. Learn how to implement JWT-based authentication securely.

Password Security

Never store passwords in plain text. Use bcrypt or similar hashing algorithms to securely store and verify passwords.

Role-Based Access Control

Implement role-based access control (RBAC) to manage user permissions and protect sensitive routes and resources.
