Why you shouldn't use local storage?

Question

If an attacker can run JavaScript on your website, they can retrieve all the data you've stored in local storage and send it off to their own domain. This means anything sensitive you've got in local storage (like a user's session data) can be compromised.

What are the disadvantages of local storage?

The downsides to local storage are major. Creating and maintaining a local storage system is expensive. The hardware and software can cost thousands of dollars depending on how much space you need. Upgrading can also be costly.

Is local storage good to use?

If it's sensitive information or data that is better suited to be stored in the server, then it shouldn't be stored in Local or SessionStorage. But if you want your user to be able to toggle light or dark mode and have that state persisted, then LocalStorage is a good option!
