Should you use localStorage?

Question

To keep it short, here's the only situation in which you should use local storage: when you need to store some publicly available information that is not at all sensitive, doesn't need to be used in a high performance app, isn't larger than 5MB, and consists of purely string data.

Should I use LocalStorage or sessionStorage?

localStorage and sessionStorage are almost identical and have the same API. The difference is that with sessionStorage , the data is persisted only until the window or tab is closed. With localStorage , the data is persisted until the user manually clears the browser cache or until your web app clears the data.

Why LocalStorage is not secure?

XSS attacks allow attackers to inject client-side scripts into Web pages viewed by other users. If someone injects their own JavaScript code into your website, they can retrieve all the data stored in the LocalStorage and send it anywhere. All sensitive data stored in LocalStorage can be stolen.
