Should cookies be turned on or off?

Cookies do not need to be completely enabled or disabled. The appropriate choice depends on what the cookie does and your privacy preferences.

Necessary cookies often support functions such as authentication, security, shopping carts, and session management. Blocking them can affect how parts of a website work.

Optional cookies used for advertising, analytics, or personalization can generally be rejected where the website provides that choice. Disabling them can reduce optional tracking but may also affect certain website features.

If a website provides cookie settings, selecting individual categories is usually more practical than blocking every cookie.
