What are the different authentication methods and how do they compare?

There are several authentication methods, including password-based, two-factor authentication (2FA), biometrics, and OAuth. Each has its pros and cons.

Can you explain the pros and cons of password-based authentication?

Password-based authentication is simple and widely used, but it's vulnerable to attacks like phishing and brute force. Users often choose weak passwords.

What about two-factor authentication? Is it worth it?

Yes, 2FA adds an extra layer of security by requiring a second form of verification, making it much harder for unauthorized access.

How does biometric authentication work?

Biometric authentication uses unique physical characteristics, like fingerprints or facial recognition, to verify identity. It's convenient but can raise privacy concerns.
