Explore best practices for clear policies, secure session and persistent cookies, expiration management, and data minimization. Stay ahead with insights on privacy trends, server-side storage, new alternatives, and evolving cookie technologies. Ensure a positive user experience while respecting privacy and security.
Cookies are small text files that websites use to store information on a user's computer or device. Cookies can be used for a variety of purposes, such as remembering a user's preferences, tracking their behavior on a website, and enabling personalized advertising. There are two main types of cookies: session cookies and persistent cookies.
In this article, we will explore the differences between session and persistent cookies, their advantages and disadvantages, and the best practices for using them. We will also discuss the potential privacy and security concerns associated with the use of cookies and strategies for minimizing these risks.

Session cookies are temporary cookies that are deleted when a user closes their browser. They are commonly used by websites to maintain information about a user's activity on a website during a single browsing session. This information can include items such as items added to a shopping cart or website preferences.
When a user visits a website, the website creates a session cookie that contains a unique identifier for that user's session. The cookie is stored on the user's device and is used to keep track of the user's activity on the website. As the user navigates the website, the cookie is updated with information such as the pages visited, items added to a shopping cart, and other preferences.
Session cookies are temporary and are automatically deleted when a user closes their browser. This means that they do not take up any space on the user's device.
Session cookies can be used to keep a user's information secure because they only last for the duration of a single browsing session.
Session cookies are easy to implement and do not require any special configuration.
Session cookies cannot be used to store information that needs to be accessed across multiple browsing sessions.
If a user closes their browser or their session expires, any information stored in a session cookie will be lost.
Persistent cookies are cookies that remain on a user's device even after they close their browser. They have an expiration date and can be used to store information that can be accessed across multiple browsing sessions. This information can include login credentials, language preferences, and other customized settings.
When a user visits a website, the website creates a persistent cookie that is stored on the user's device. The cookie contains a unique identifier that is used to track the user's activity on the website across multiple browsing sessions. As the user navigates the website, the cookie is updated with information such as the user's login credentials, language preferences, and other customized settings.
Persistent cookies can be used to store information that needs to be accessed across multiple browsing sessions, such as login credentials and language preferences.
Persistent cookies can be used to track a user's behavior on a website over time, which can be used to personalize the user's experience.
Persistent cookies can be used to remember a user's preferences, such as their preferred layout or font size.
Persistent cookies take up space on the user's device, which can slow down their browsing experience.
Persistent cookies can be used to track a user's behavior across multiple websites, which can be seen as a privacy concern.
Persistent cookies can be used to store sensitive information, such as login credentials, which can be a security risk if the cookie is accessed by an unauthorized party.
Here's a recap of the comparison again:
| Feature | Session Cookies | Persistent Cookies |
|---|
| Lifespan | Temporary, deleted when browser closes | Persistent, remains on device after browser closes | |
| Expiration Date | No expiration date | Set expiration date by website | |
| Storage | Doesn't take up device space | Takes up device space | |
| Information Stored | Activity within a single session (shopping cart, form data) | Information across multiple sessions (login, preferences, settings) | |
| Security | More secure due to shorter lifespan | Less secure, sensitive data at risk | |
| Privacy | Less intrusive, limited tracking | More intrusive, tracks across websites | |
| Advantages | Secure, easy to implement, no space needed | Saves user time, personalization, remembers preferences | |
| Disadvantages | Limited use, data lost on session end | Privacy concerns, takes up space, security risks | |
| Examples | Shopping cart functionality, login credentials (same session), form data | Login credentials (across sessions), language preferences, personalized advertising | |
The best choice depends on your needs and priorities. If privacy is paramount, session cookies offer a lighter touch. But if convenience and personalization are key, persistent cookies might be your jam. Remember, you can often control cookie settings on websites to strike a balance between functionality and privacy.

When using cookies on a website, there are several best practices that can help ensure that they are used effectively and responsibly.
By following these best practices, website owners can help ensure that their use of cookies is effective, secure, and respectful of user privacy. We also have an in-depth article on cookie consent best practices.
As technology continues to evolve, the future of session cookies and persistent cookies is likely to change as well. Here are a few potential trends to keep an eye on:
It is difficult to predict exactly how session cookies and persistent cookies will evolve in the future. However, website owners should stay up-to-date on emerging trends and be prepared to adapt to changes in technology and regulations. By doing so, they can continue to provide a positive user experience while also respecting user privacy and security. For more information, check out our article on Preparing for a Cookie-Free Future.
Session cookies and persistent cookies are both important tools that website owners can use to improve the user experience and personalize their website. Session cookies are temporary and are used to maintain information about a user's activity during a single browsing session. Persistent cookies are stored on a user's device and can be used to store information that can be accessed across multiple browsing sessions.
While cookies can be very helpful, they can also pose a privacy risk if not used responsibly. Website owners should follow best practices such as providing clear and concise cookie policies, using secure cookies, and minimizing the amount of information stored in cookies. They should also provide users with the ability to opt-out of certain types of cookies.
