No, they don’t make it easier for you to be hacked. Cookies are just small text files used as temporary storage on your computer. Websites use them to remember who you are – just like a store card for a shop. Cookies don’t contain your credit card number or your computer’s password, and they are only ever sent back to the website that created them in the first place. Turning off cookies just means that websites won’t remember that you are already logged in and they might keep showing you the same advert, because they won’t know that you’ve already seen it.
