Key Takeaways

Cookies give websites memory by storing small browser records for logins, shopping carts, preferences, analytics, and advertising.
Cookies are data, not programs: they cannot act like viruses, but stolen login cookies can enable session hijacking.
First-party cookies typically support the site you are visiting, while third-party cookies can enable tracking across multiple websites.
Choose “necessary only” or reject optional cookies to preserve essential features while limiting analytics and advertising.
Blocking third-party cookies offers a practical balance between privacy and functionality; blocking all cookies may break logins, carts, payments, and embedded tools.
Rejecting cookies does not stop all tracking because sites may also use server logs, IP addresses, tracking pixels, URL parameters, and browser fingerprinting.
Deleting cookies can sign you out and reset preferences, but it does not erase account records, server logs, or data companies already collected.
Private or incognito mode is not anonymous browsing; it mainly isolates and removes local session data after private windows close.
Secure authentication cookies should use protections such as Secure, HttpOnly, and SameSite; see the MDN cookie guide.
Best default: keep essential cookies, limit optional analytics and advertising cookies, enable browser tracking protections, and clear cookies after using shared devices.

Jay's Recommendation

On a network you don't trust?

These videos explain security concepts. NordVPN is what I use when the connection needs protection: encrypted traffic, a kill switch, and servers for public Wi-Fi.

Kill switchStops leaks if it drops
