Multifactor authentication (MFA) is a security method that requires users to provide two or more pieces of evidence to verify their identity before accessing a system. MFA can use different types of factors, such as something the user knows (e.g., password, PIN, security question), something the user has (e.g., token, smart card, mobile device), or something the user is (e.g., fingerprint, face, voice). MFA provides a layered approach to logging in to systems that contain an organization's most valuable intellectual property, as it makes it harder for unauthorized users to gain access by compromising one factor alone. MFA can also prevent phishing, brute force, and credential theft attacks12. References = CompTIA Project+ PK0-005 Certification Study Guide,
