What is a common outcome of utilizing multi-factor authentication?

Utilizing multi-factor authentication (MFA) significantly enhances security by requiring users to provide two or more verification factors to gain access to an account or system. This approach adds an additional layer of security beyond just a username and password, which can often be compromised through various means, such as phishing or brute-force attacks. By implementing MFA, even if an attacker manages to obtain a user's password, they would still need the second factor (such as a one-time code sent to a mobile device or a biometric scan) to successfully access the account. This multi-layered defense makes unauthorized access much more difficult, thereby helping to protect sensitive information and systems.

In contrast, faster email delivery times, reduction in email storage needs, and increased vulnerability to phishing attacks do not directly relate to the purpose or benefits of multi-factor authentication. These are concerns that arise from different areas of email security and performance, but they are not outcomes associated with the implementation of MFA.
