Especially for sensitive or classified information, multifactor identification is a must. MFA is any security system that requires more than one method of user verification. With MFA, systems combine 2 or more security methods from 2 or more different categories. Categories include: knowledge factors, or things you know, like a password or security question; possession factors, or physical things -- like a key; inherence factors, or biological traits -- like fingerprint scans; location factors -- usually determined with a smartphone’s GPS; and time factors, which is a logical barrier.
