Multifactor authentication (MFA) significantly increases network security by requiring more than one form of verification. This method makes it more challenging for unauthorized users to gain access even if they have compromised one credential type, such as a password. This reduces the likelihood of unauthorized access, compared to using only passwords. Other answers are partly correct but do not fully align with the primary intent of MFA to enhance access security by layering verification methods.
