What is MFA?
Multi Factor Authentication strengthens login security by requiring users to provide multiple forms of verification typically combining something they know (a password), something they have (a mobile device or hardware token), and something they are (a biometric). Because MFA requires an attacker to compromise multiple independent factors simultaneously, it is one of the most effective controls available for preventing unauthorized access. Even if a user’s password is stolen through phishing or a data breach, MFA ensures that the attacker cannot log in without also possessing the user’s physical device or biometric. Most modern compliance frameworks and cyber insurance policies now mandate MFA as a baseline security requirement.
