News This $18 key can protect you from hackers

Your online accounts should be protected with more than just a password. And using a cheap device called YubiKey can help keep you from being hacked.

By now you've probably heard you should be using two-factor authentication, often called 2FA, to log in to your accounts. If you're using 2FA, you need an additional code to access your email, Facebook or other accounts. This is often sent via SMS, which may not be the most secure.

YubiKey, created by Yubico, is one solution. The $18 key connects to a USB port on your computer and tells a service, like Gmail, that you are you.
