Is it safe to use localStorage?

Question

No. localStorage is accessible by any webpage, and if you have the key, you can change whatever data you want. That being said, if you can devise a way to safely encrypt the keys, it doesn't matter how you transfer the data, if you can contain the data within a closure, then the data is (somewhat) safe. 6 янв. 2015 г.

Can local storage be hacked?

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.

Is using LocalStorage good?

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!
