Stop Storing Sensitive Data in Local Storage: Do This Instead!

Storing sensitive data like access tokens in local storage is a big no-no! Here's why:

1️⃣ Local storage is vulnerable to XSS attacks.

2️⃣ Tokens in local storage can be easily accessed by JavaScript, increasing the risk of compromise.

🔒 The Solution?

Store all tokens and sensitive data in HTTP-only cookies. Here's why it's better:

  • Cookies are secure and inaccessible to JavaScript.
  • They support automatic handling of token refreshing.
  • Signed cookies ensure data integrity.

What I’m Building 🚀

I’m working on creating a secure Node.js + React app that:

✅ Never store sensitive data in local storage.

✅ Is scalable for big systems.

✅ Includes an easy-to-follow tutorial with a GitHub repo link!
