🔐 Authentication: Verifying the identity of users. It's the process of ensuring users are who they claim to be.

In Node.js, popular libraries like Passport.js simplify this process by providing strategies for local and third-party (OAuth) authentication.

🔓 Authorization: Determining what authenticated users are allowed to do. This step decides if a user has permission to access specific resources or perform actions.

Tools like JSON Web Tokens (JWT) and roles-based access control (RBAC) are commonly used to handle authorization in Node.js applications.

🌟 Key Libraries:

• Passport.js: A versatile middleware for authentication.

• JWT: Securely transmit information between parties.

• Bcrypt: Safely hash and store passwords.

Implementing strong authentication and authorization ensures your Node.js applications are secure and your users' data is protected.
