The primary benefit of implementing multi-factor authentication (MFA) is increased security. MFA requires users to provide multiple forms of verification before gaining access to sensitive information or systems, typically combining something they know (like a password), something they have (like a token or smartphone), or something they are (like a fingerprint). This layered approach significantly reduces the risk of unauthorized access, making it much harder for attackers to compromise accounts. Consequently, MFA is widely considered a best practice for safeguarding user accounts.
