What are the best practices for authentication in a MERN stack application?

When implementing authentication in a MERN stack, consider using JWT for token-based authentication, secure password storage with bcrypt, and implementing role-based access control.

How can I securely store user passwords?

You should use bcrypt to hash passwords before storing them in your database. This adds a layer of security by making it difficult for attackers to retrieve the original passwords.

What is JWT and why should I use it?

JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It's widely used for authentication because it allows stateless sessions and can be easily verified.

Can you explain role-based access control?

Role-based access control (RBAC) restricts system access to authorized users based on their roles. This helps in managing permissions efficiently and enhances security.
