How can I generate secure tokens for my application?

You can generate secure tokens using libraries like JWT or UUID. Would you like to know more about a specific method?

What's the difference between JWT and UUID?

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information. JWT is often used for authentication, while UUID is used for unique identification.

Which one is more secure for user authentication?

JWT is generally more secure for user authentication because it can be signed and encrypted, allowing for secure transmission of claims.

Can you show me an example of generating a JWT?

Sure! In Node.js, you can use the 'jsonwebtoken' library. Here's a simple example: const jwt = require('jsonwebtoken'); const token = jwt.sign({ userId: 123 }, 'your_secret_key');.
