How to determine what plugins use cookies in wordpress sites

Cookies are small text files that are stored on the user’s computer when they visit a website. They help website owners to keep track of the activities of individual visitors and to compile reports on the use of their websites.

In WordPress, cookies are used by a large number of plugins and themes. If you’re not sure which ones, it’s worth taking a look at your plugin or theme’s documentation to see which ones use cookies.

What are Cookies?

The purpose of a cookie is to store a piece of information on the user’s computer. When a user visits a website, the website can read the cookie and then use that information to identify the user. Cookies help websites remember individual user preferences, track how users are using a site, and provide statistics about how people are using a site.
There are two types of cookies: session cookies and persistent cookies. Session cookies expire after the user logs off from their computer or after the browser cache times out. Persistent cookies stay on a computer until they are deleted, which means that they can be used to track the activity of a user over time.
There are four main ways that cookies can be used on websites:
– Authentication Cookies: These cookies help websites remember who you are (for example, if you have logged in before).
– Traffic Lights Cookies: These cookies allow websites to distinguish between different types of traffic (for example, normal vs. credit card traffic).
– Advertising Cookies: These cookies collect information about how users are using a website so that adverts can be targeted more accurately.
– Functionality Cookies: These cookies allow websites to perform specific actions based on the information stored in them (

How Do Cookies Work?

Cookies are small files that are stored on your computer by websites that you visit. Cookies help websites to remember the information about your visits so that they can improve your experience when you return to the site. For example, a website might set a cookie to remember your username so that you don’t have to enter it every time you log in. Cookies also help websites to track the traffic on their sites. This is useful for understanding how people are using the site and for making changes that can improve the user experience.

Most cookies are automatically deleted when you close your browser, but some cookies (for example, those used by Google Analytics) stay on your computer until you delete them. If you want to disable all cookies on your computer, you can do this in the settings of your browser. However, disabling cookies will probably impact the functionality of many websites. It’s always best to consult the website’s privacy policy before deciding whether or not to disable cookies.

How to Find Out What Cookies Are Used by a Plugin

To find out what cookies a plugin is using, you can use the wp_set_cookie function. This function takes two arguments: the name of the cookie, and the value of the cookie. The following example sets the Cookie header for the current WordPress site to “wordpress_isite”:

wp_set_cookie(‘wordpress_isite’, ‘1’);

You can also use the wp_get_cookies function to get a list of all cookies on a site. The following example returns a list of all cookies on the current WordPress site:



One of the most important things you can do when building a WordPress site is to make sure that all of your plugins use cookies in a responsible way. Cookies are small pieces of data that are stored on your device by certain plugins and used by WordPress to provide features such as logging into your site. By understanding which plugins use cookies, you can better manage and protect your website from potential security risks.
