Is it safe to use sessionStorage?

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.

Should I use cookies or sessionStorage?

For most cases, we use the localStorage object if we want some data to be on the browser. If we want it on the server, then we use cookies, and the sessionStorage is used when we want to destroy the data whenever that specific tab gets closed or the season is closed by the user.

Why you should not use localStorage?

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.
