Two-Factor Authentication (2FA) adds an extra layer of security to your online accounts. Instead of just using a password, 2FA requires a second verification method, like a code from your phone or an authenticator app. This makes it much harder for hackers to access your accounts, even if they know your password. Think of it as having two locks on your door instead of just one!
This practice quiz will test your understanding of 2FA concepts and terminology. It's a great way to reinforce what you've learned and identify any areas where you might need to brush up. Let's get started!
