Learn how to protect yourself online - featuring tips on haveibeenpwned, AI demos and 2FA/MFA authentication.

First up, I have some sobering news. Almost all of our personal information has likely been stolen at one point or another. This could include our names, addresses, phone numbers, email addresses, and even passwords. Cybercriminals are constantly searching for vulnerabilities in systems where this information is stored, and unfortunately, they often find them.

However, there are steps we can take to protect ourselves. One tool that can help is called "haveibeenpwned." It's a website where you can check if your email address has been compromised in any data breaches. If it has been compromised, you'll want to change the password associated with that account immediately.

Next, let's talk about something more futuristic: artificial intelligence (AI). AI refers to machines that are capable of performing tasks that would typically require human intelligence, such as learning from experience or recognizing speech patterns. 

To give you a live demonstration of AI in action - think about Siri on an iPhone - ask her anything, and she will respond using natural language processing powered by machine learning algorithms running behind the scenes.

Finally, explain two-factor authentication (2FA) and multi-factor authentication (MFA). These methods add an extra layer of security when logging into accounts online. 2FA requires users to enter both their password and a unique code sent via text message or generated by an app on their phone before being allowed access into the system; MFA requires additional credentials beyond just the user's login-password pair – such as biometric identification through facial recognition or fingerprint scans – further reducing risk for unauthorized access attempts.
