Multi-Factor Authentication (MFA)

What Is Multi-Factor Authentication (MFA)?

Short definition:
Multi-Factor Authentication (MFA) requires users to verify their identity using two or more methods before accessing systems or accounts.

What this actually means for a business:
MFA significantly reduces the risk of account compromise, even if a password is stolen.

Common misconception:
MFA is inconvenient or unnecessary. In reality, it’s one of the most effective security controls available.

When this matters:
Any system containing sensitive data or accessible from the internet should use MFA.
