📚 Topic Summary
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 sent to your phone or an app. This makes it much harder for hackers to access your accounts, even if they know your password. Think of it like having two locks on your front door instead of just one!
This activity will help you understand the core concepts of 2FA through vocabulary building, fill-in-the-blanks, and critical thinking exercises. Get ready to boost your cybersecurity knowledge!
