What are the differences between session storage and cookies?

Session storage and cookies are both used to store data in the browser, but they have key differences. Session storage is temporary and lasts only for the duration of the page session, while cookies can persist for a specified duration even after the browser is closed.

Can you explain how session storage works?

Sure! Session storage allows you to store data for the duration of a page session. This means that the data is available as long as the browser tab is open. Once the tab is closed, the data is cleared.

What about cookies? How do they work?

Cookies are small pieces of data stored on the user's computer by the web browser. They can have an expiration date, allowing them to persist even after the browser is closed. Cookies are often used for tracking user sessions and preferences.

Which one is better for user authentication?

For user authentication, cookies are generally preferred because they can persist across sessions and can be set with secure flags. Session storage is more suitable for temporary data that doesn't need to be retained after the session ends.
