Multi-Factor Authentication (MFA)
What is Multi-Factor Authentication (MFA)?
Multi-factor authentication is a security system that requires more than one method of verification from independent categories of credentials to verify a user’s identity. This typically involves something the user knows (password), something they have (phone), or something they are (fingerprint).
Why It Matters
-
It provides a much stronger defense than passwords alone, as an attacker would need to compromise multiple factors to gain access.
-
MFA significantly reduces the success rate of phishing, credential stuffing, and other common account takeover attacks.
-
It is a standard requirement for many security certifications and regulatory compliance frameworks.
