For example, requiring a password and a shared secret is still considered SFA as they both belong to the knowledge authentication factor type.

A is good, but adaptive MFA is better

2FA stands for two-factor authentication, which is a security process that enables organizations to increase the security of their applications, systems, and websites. SMS 2FA is cheap and easy for employees to use but vulnerable to cyberattacks. The use of SMS for 2FA has been discouraged by the National Institute of Standards and Technology (NIST), saying it is vulnerable to various portability attacks and malware issues.

Critics argue that text messages are not a true form of 2FA since they are not something the user already has but rather something the user is sent, and the sending process is vulnerable.
