Password Security — 20 Questions

  1. What makes a strong password? (12+ characters, mix of uppercase/lowercase, numbers, symbols)
  2. What is a password manager? (Tool that generates and stores strong unique passwords)
  3. What is two-factor authentication (2FA)? (Requires second verification — code, biometric, or hardware key)
  4. What is the most common password? ("123456" — still used by millions)
  5. How often should you change passwords? (Only when compromised — unique strong passwords per site is more important)
  6. What is a passphrase? (Multiple random words — longer but memorable — "correct horse battery staple")
  7. What is biometric authentication? (Using fingerprint, face ID, or iris scan for verification)
  8. What is a hardware security key? (Physical device (YubiKey) for 2FA — most secure option)
  9. What is single sign-on (SSO)? (Login once to access multiple applications)
  10. What is credential stuffing? (Using stolen passwords from one breach to access other accounts)

Online Privacy & Safe Browsing — 25 Questions

  1. What is a browser cookie? (Small file storing user preferences and session data)

  3. What is a VPN? (Encrypts traffic and hides IP address)
  4. What is the Tor browser? (Routes traffic through multiple nodes for anonymity)
  5. What does HTTPS padlock mean? (Connection is encrypted — data is secure in transit)

  13. How do you spot a phishing email? (Check sender address, look for urgency/threats, hover over links, watch for typos)
  14. What is HTTPS vs HTTP? (HTTPS encrypts data; HTTP sends in plaintext — never enter passwords on HTTP)
  15. What is a man-in-the-middle attack on public WiFi? (Attacker intercepts traffic between you and the hotspot)

❓ Frequently Asked Questions

What are the most important internet security practices?

Use strong unique passwords + password manager, enable two-factor authentication, keep software updated, use HTTPS websites only, be suspicious of emails/links, use a VPN on public WiFi, and back up data regularly.

What is the biggest internet security threat in 2026?

Phishing remains the #1 threat — it accounts for over 80% of successful cyberattacks. AI-powered phishing (using deepfakes and personalized messages) is making attacks more convincing than ever.
