Which authentication method offers enhanced security by verifying a user's identity with a characteristic inherent to them that cannot be forgotten or shared?
Using biometric authentication enhances security by verifying a user's identity based on unique physical characteristics, such as fingerprints, facial recognition, or iris scans. These inherent traits cannot be forgotten or shared, making biometric authentication highly secure. Implementing complex password policies and enforcing regular password changes can strengthen password security but still rely on information that can be forgotten or shared. Issuing security tokens adds an extra layer of security, but tokens can be lost or stolen.
