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.

πŸ”’ 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 πŸš€

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

βœ… Never store sensitive data in local storage.

βœ… Is scalable for big systems.

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