Question 1

True or false: Some 2FA methods can be compromised by a SIM swap attack.

Accepted Answer

True. SMS-based 2FA is vulnerable to SIM swapping, where attackers transfer your number to their device to receive codes.

Question 2

True or false: Two-factor authentication always requires a password plus a code sent via SMS.

Accepted Answer

False. 2FA can use biometrics, hardware tokens, or authenticator apps—SMS is just one common, less secure method.

Question 3

True or false: Using the same 2FA method for all accounts increases your overall security.

Accepted Answer

False. Reusing one method creates a single point of failure; diversifying factors (e.g., hardware key for email) is safer.

Question 4

True or false: Hardware security keys are immune to all forms of remote hacking.

Accepted Answer

False. Hardware security keys are highly phishing-resistant, but they are not immune to all remote hacking. Vulnerabilities in firmware or protocol could allow remote attacks, proving no system is 100% secure.

Question 5

True or false: Phishing attacks can bypass two-factor authentication in real time.

Accepted Answer

True. Attackers use reverse proxy phishing to intercept credentials and session tokens, defeating 2FA instantly.

Question 6

True or false: Google reported that 2FA blocks 100% of automated bot attacks.

Accepted Answer

True. Google's 2019 security research found that any form of two-factor authentication blocks 100% of automated bots, 99% of bulk phishing, and 66% of targeted attacks.

Question 7

True or false: Two-factor authentication was invented in the early 2000s.

Accepted Answer

False. The concept dates back to 1970s military systems; RSA SecurID tokens popularized it commercially in the 1980s.

Question 8

True or false: Push notification 2FA can be exploited via 'MFA fatigue' attacks.

Accepted Answer

True. Attackers spam users with push prompts until they accidentally approve, granting access without a password.
