Question

How can I secure my API from unauthorized access?

Answer 1

You can secure your API by using API keys, OAuth2, or JWT (JSON Web Tokens). Here's an example of implementing JWT in a Node.js application:

const jwt = require('jsonwebtoken');
const secretKey = 'yourSecretKey';

const token = jwt.sign({ userId: 123 }, secretKey, { expiresIn: '1h' });
