Acronym for Multi-Factor Authentication—requiring multiple verification factors for access.
MFA stands for Multi-Factor Authentication. See 'Multi-Factor Authentication' for the full definition. MFA is required by most compliance frameworks and increasingly expected by cyber insurers.
Why It Matters
The DSC Perspective:
MFA is non-negotiable for modern security. Compliance frameworks require it, insurers expect it, and attackers target accounts without it. Enable MFA on every account that supports it.
