Websites are racing to patch the Heartbleed bug, the worst security hole the Internet has ever seen.
As sites fix the bug on their end, it's time for you to change your passwords. The Heartbleed bug allowed information leaks from a key safety feature that is supposed to keep your online communication private -- email, banking, shopping, and passwords.
Don't change all your passwords yet, though. If a company hasn't yet updated its site, you still can't connect safely. A new password would be compromised too. (And here's what you need to know about how Heartbleed affects your tax return.)
Many companies are not informing their customers of the danger -- or asking them to update their log-in credentials. So, here's a handy password list. It'll be updated as companies respond to CNN's questions.
