How does multi-factor authentication benefit server access?

Multi-factor authentication enhances access protection by requiring users to provide two or more verification factors to gain access to a server or system. This additional layer of security significantly decreases the likelihood of unauthorized access because even if a password is compromised, the attacker would still need the additional authentication factor, such as a biometric scan or a one-time code sent to a mobile device, to gain entry. This multifaceted approach makes it much harder for malicious actors to breach systems compared to a single factor, such as only requiring a password.

While other options may touch on aspects related to user management or convenience, they do not address the primary of enhancing security that multi-factor authentication aims to achieve. Reducing the need for usernames does not align with the purpose of multi-factor authentication, neither does streamlining the login process, as the additional steps can make logging in more complex. Additionally, enabling unlimited user accounts does not relate to the foundational security benefits that multi-factor authentication provides.
