What are Internet Cookies?

Have you ever visited a website and then almost immediately a pop-up appears asking if you want to accept or reject cookies? If the answer is yes, then it’s important to know what cookies are and how they work.   

What is a cookie?  

Internet cookies are small files that are sent from the website you are visiting to your browser. The browser (Chrome, Safari, Firefox) then processes and stores the small file. Information commonly stored includes your device, location, log-in information, online activity and more. Different types of cookies include:  

Session Cookies: Are deleted immediately after closing the browser. These are commonly seen to keep items in a cart after clicking on another website 

Persistent Cookies: Save data such as username and password data for an extended period of time 

Third-Party Cookies: Store online activity (what site you visited, how long you spent on it, what you clicked on). Advertisers specifically utilize third-party cookies to target individuals with specific ads. 


  • They grant access to websites  
  • Information such as name, address, and phone number auto-fill when filling out an online form  
  • Items left in a shopping basket will be there when you return to the site 
  • The login process is easier with a saved username and password  


  • Third-party cookies can contain a significant amount of information such as online behavior, preferences, and location that is then used for advertising 

Only accept cookies if you know the website is secure. Next to the URL address, if there is a padlock symbol, that means the site is secure.
