How does multi-factor authentication (MFA) enhance conversion security?

Multi-factor authentication (MFA) significantly enhances conversion security by introducing an additional layer of security through verification. This approach requires users to provide multiple forms of identification before granting access to sensitive information or systems. Typically, MFA combines something the user knows (like a password), something the user has (such as a mobile device for receiving a verification code), and sometimes something the user is (biometric data like fingerprints).

The strength of MFA lies in its ability to reduce the risk of unauthorized access. Even if a password is compromised, an attacker would still need the second form of identification to gain access, which drastically increases security. This layered defense mechanism makes it much harder for malicious actors to breach accounts, thus enhancing overall conversion security.

The other choices do not directly relate to enhancing security. For instance, single sign-on may improve user convenience but does not inherently increase security levels. Maintaining historical records is instrumental for auditing and compliance but does not provide real-time protective measures against unauthorized access. Improving software compatibility is crucial for seamless integrations but does not impact the security of the conversion process itself.
