CookieSwap is a web-based application designed to help users easily manage and share their browser cookies. It allows users to store, sort, and organize their cookie data, as well as to quickly swap out cookies from different browsers. This allows users to easily access sites and services that require authentication, such as banking websites, without having to manually enter their credentials each time. It also makes it easier to keep track of multiple accounts, such as multiple email accounts, without having to log out and log back in. The application also includes useful features such as a timer that reminds users to clear their cookies periodically and a search feature that allows users to quickly find a specific cookie.
