What are some alternatives to multi-factor authentication?

There are several alternatives to multi-factor authentication, such as biometric authentication, hardware tokens, and single sign-on solutions.

Can you explain how biometric authentication works?

Biometric authentication uses unique physical characteristics, like fingerprints or facial recognition, to verify a user's identity.

What are the pros and cons of using hardware tokens?

Hardware tokens provide strong security but can be lost or damaged. They also require users to carry an additional device.

Is single sign-on a secure option?

Single sign-on can be secure if implemented correctly, but it can also create a single point of failure if compromised.
