How to effectively prevent cookies from leaking secrets

Cookies are data files sent by a web server to a computer that record information such as usernames, passwords, and information about user interests. Moreover, the usernames and passwords in the cookies file received by many websites are even stored in plain text, which is even more insecure. Therefore, it is necessary to delete the cookies file.
If you use Windows 9X/Me, open the folder and delete all files except index.dat. If you are using Windows 2000/XP, open the folder and delete all files except index.dat.

Of course, we can also execute a batch command, enter the following command:

xxcopy c:\\windows\\cookies\\*.* /s /h /yy /rs /xindex.dat

or xxcopy "C:\\Documents and Settings\\Administrator\\Cookies\\*.*" /s /h /yy /rs /xindex.dat

Then put it on your desktop, Clear your cookies at any time.

In addition, you can also open IE, select "Tools→Internet Options", select the "Hide" tab, and then use the mouse to adjust the Cookie slider to the highest point, indicating that cookies are blocked, so that you can use it once and for all. Every time I delete it. However, some forums require the opening of cookies, and if they are not open, they will not be able to access them.
