Is local storage safer than cookies?

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.
