This extra step keeps strangers out of your account. It works even if someone learns your password. It may feel like one more thing to do. But it is one of the best ways to stay safe. You are doing something smart here. It gets easy fast.

Sometimes a website asks for a short code after your password. The code is a quick way for the site to know it is you. This lesson shows you what it is. It also shows you how to use it.

The code only works for a few minutes. If it stops working, ask the website to send a new one. That is normal. You did nothing wrong.
Only enter a code right after you log in yourself. Never read or send your code to anyone who contacts you. This is true even if they sound official. A real company will never call you to ask for it.
