Is localStorage safe in react?

Is it safe to use localStorage?

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.

Is it safe to store token in localStorage react?

If you store it inside localStorage, it's accessible by any script inside your page. This is as bad as it sounds; an XSS attack could give an external attacker access to the token. To reiterate, whatever you do, don't store a JWT in local storage (or session storage).

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 localStorage a security risk?

localStorage is a property that allows JavaScript sites and apps to save key-value pairs in a web browser with no expiration date. This means the data stored in the browser will persist even after the browser window is closed.
