Differences between cookie and Session:

1. Cookie (name, value, expiration time, path, and domain) data is stored in the client's browser, and session data is stored on the server.

2. Cookies are not very secure. Others can analyze the Cookies stored locally and perform cookie spoofing. For security reasons, session should be used.

3. The session will be stored on the server for a certain period of time. When the number of accesses increases, it will occupy the performance of your server. Cookie should be used in consideration of reducing server performance.

4. data stored in a single cookie cannot exceed 4 kb. Many browsers limit that a site can store up to 20 cookies.

5. personal suggestion: store important information such as login information as Session, and store other information in cookies if necessary.
