Keeping Sensitive Information Out

You do not need to memorize a long list of dos and don'ts to use AI safely. There is one rule that covers almost everything: never paste anything into an AI that you would not want stored or seen by a stranger. In this lesson you will turn that rule into clear, practical habits so you get AI's help without giving away what matters.

Some things should simply never go into a chatbot: passwords, PINs, full credit card numbers, government ID numbers, and bank logins. The AI does not need them to help you, and putting them in a stored chat is a needless risk. If a prompt seems to require a secret, you can almost always remove or fake it instead.
