What are some examples of two-factor authentication methods?
Two-factor authentication (2FA) methods include SMS codes, authenticator apps, hardware tokens, and biometric verification.
Can you explain how an authenticator app works?
Sure! An authenticator app generates time-based one-time passwords (TOTPs) that you enter along with your password.
Are there any security risks with SMS-based 2FA?
Yes, SMS-based 2FA can be vulnerable to SIM swapping and interception, making it less secure than other methods.
What is the most secure 2FA method?
Hardware tokens are often considered the most secure, as they are physical devices that generate codes and are not susceptible to online attacks.
