What are the different types of two-factor authentication?

There are several types of two-factor authentication (2FA), including SMS-based, app-based, hardware tokens, and biometric methods.

Can you explain how SMS-based 2FA works?

Sure! SMS-based 2FA sends a one-time code to your mobile phone via text message, which you enter to verify your identity.

What are the pros and cons of using app-based 2FA?

App-based 2FA, like Google Authenticator, is more secure than SMS because it doesn't rely on your phone number, but it requires you to have the app installed.

Are hardware tokens more secure than other methods?

Yes, hardware tokens are generally considered very secure as they generate codes independently of your devices and are less susceptible to phishing.

What about biometric methods? How do they work?

Biometric methods use unique physical characteristics, like fingerprints or facial recognition, to verify identity, providing a high level of security.
