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

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

Can you explain the pros and cons of using passwords?

Passwords are easy to implement but can be weak if users choose simple ones. They are also vulnerable to phishing attacks.

What about biometrics? Are they more secure?

Biometrics, like fingerprints or facial recognition, are generally more secure but can raise privacy concerns and may not work for everyone.

How does two-factor authentication improve security?

Two-factor authentication adds an extra layer of security by requiring a second form of verification, making it harder for unauthorized users to gain access.
