Persistent cookies are encrypted cookie files that help websites remember your information and settings when you visit in the future. But these cookies remain on your device, even after you've closed out the browser. Persistent cookies are stored on your browser, resulting in faster and more convenient access since, for example, you don't have to login again. Persistent cookies can also include language selections or your customized settings.
Unlike persistent cookies, session cookies are considered necessary cookies for a website to function, and these temporary files delete once you close your browser. Conversely, persistent cookies stay in one of your browser's subfolders until you delete them manually or your browser deletes them based on its expiration date.
Persistent cookies are small files that wait and record your preferences as you move about a webpage. On your first visit, the website is presented in default mode. During your visit, you select your preferences and these preferences are remembered, through the use of the persistent cookie, the next time you visit the site.
For example, a website may offer its contents in different languages. On your first visit, you may choose to have the content delivered in French and the site may record that preference in a persistent cookie set on your browser. When you revisit that site it will use the cookie to ensure that the content is delivered in French.
Persistent cookies can save your information even after you've closed out your browser, potentially enhancing your online experience.
Persistent cookies do serve a purpose, and are partially responsible for streamlining your online experience. Persistent cookies are the reason your login information autofills on selected sites.
Besides authentication, other websites' features made possible by persistent cookies include: language selection, theme selection, menu preferences, and internal site bookmarks or favorites. Persistent cookies also allow you to personalize your ad preference online.
However, persistent cookies can track you across websites to build an online profile of your behavior and preferences. The good news is that due to data privacy regulations, websites must get your consent to collect your data for tracking or advertising purposes.
While cookies help streamline your internet, it's necessary to manage your cookie use for optimum efficiency. When you store up too many cookies (or site data), your device will inevitably slow down, and you may see decreased browser performance. Plus, too much stored data can pose a security risk. That's why it's recommended to regularly clear your cookies, cache, and browsing history.
First, access your browser settings to manage cookies. Here is our step-by-step guide on how to enable and disable cookies on any browser. Then, use an ad blocker with cookie and tracker blocking capabilities to further enhance your online security.
