🚀 How Do You Handle Authentication Using JWT in Node.js? JWT (JSON Web Token) is a popular authentication method in Node.js for securing APIs and user authentication. 🔐 🔥 Steps to Implement JWT Authentication: ✅ User Login & Token Generation – When a user logs in, generate a JWT using jsonwebtoken. ✅ Sign the Token – Use a secret key (process.env.JWT_SECRET) to sign the token. ✅ Send Token to Client – Store it in HTTP headers, localStorage, or cookies (securely). ✅ Verify Token on Requests – Middleware checks JWT validity for protected routes. ✅ Handle Token Expiry & Refresh – Implement refresh tokens to extend sessions securely. 💡 JWT ensures secure, stateless authentication for your Node.js applications! 🎉 #NodeJS #JWT #Authentication 🚀 #Security #ExpressJS #APISecurity #CyberSecurity #WebDevelopment #JavaScript #CodingTips #DeveloperLife 💻✨
