Are cookies more secure than local storage?
Always assume the worse. While cookies do have a “secure” attribute that you can set, that does not protect the cookie in transit from the application to the browser. So it’s better than nothing but far from secure. Local storage, being a client-side only technology doesn’t know or care if you use HTTP or HTTPS.
Which is better sessionStorage vs localStorage?
sessionStorage is similar to localStorage ; the difference is that while data in localStorage doesn’t expire, data in sessionStorage is cleared when the page session ends. A page session lasts as long as the browser is open, and survives over page reloads and restores.
Cookies and local storage serve different purposes. Cookies are mainly for reading server-side, whereas local storage can only be read by the client-side . Apart from saving data, a big technical difference is the size of data you can store, and as I mentioned earlier localStorage gives you more to work with.
