# Cookie killer

The Versatile Cookie Killer invalidates all cookies in `cookies.txt`. \
This function isn't exactly needed anymore as we have a **Cookie Refresher** which is arguably a lot more useful (it invalidates all cookies and then makes its own). \
However, I don't see any reason to remove it so it is staying.

It essentially works by logging out of the account with the cookie, which ends the session and therefore **invalidates** the cookie. If there are multiple cookies for the account, it only invalidates the one you have access to instead of all, this is unlike the Cookie Refresher which invalidates all cookies linked to the account.

I can only recommend this if you really need to spite someone. Otherwise, use the Cookie Refresher and don't waste the cookies.
