What is cookie?

Most websites provide a "remember me" functionality, enabling users to conveniently log in without the need to input their username and password each time. This is accomplished through the utilization of cookies, which are petite data files that are stored on the hard drive of your computer. Upon your initial visit to a website with a cookie, the website or server places a cookie on your computer's hard drive. Subsequently, whenever you make a request to the server, it reads the cookie, allowing the web server to recognize you and retain your preferences on the website. Consequently, you can effortlessly log in without the requirement of re-entering your username and password.

It is important to note that different browsers may save cookies in distinct formats. For instance, cookies in Chromium-based browsers are stored in the SQLite version 3 format. Moreover, the credentials will persist in your browser until you manually delete specific cookies, clear all cookies, or until the cookie expires (as determined by the website administrator). As an example, in WordPress, the cookies expire after being stored for a duration of two weeks.

Technically speaking, a cookie is a data fragment transmitted from a web server to your browser. This data enables the identification of the user and the retention of their website preferences.
