MFA Is Not a Security Checkbox

Multi-factor authentication is often treated like a light switch: turn it on, receive a compliance-shaped glow, and move on.

But MFA changes the question. Once a business asks people to prove who they are with more than a password, it also has to decide what happens when the phone is lost, the authenticator is replaced, an employee leaves, or an attacker convinces someone to approve a request.

The useful question is not “Do we have MFA?” It is “Can the right person recover access without creating a new hole?” That requires documented recovery, a short list of people who can reset authentication, and a review of which accounts have more power than they need.

MFA is valuable because it makes stolen passwords less useful. It becomes much more valuable when the surrounding process does not turn account recovery into an informal help-desk conversation with no record.

For a small business, the next step after enabling MFA is simple: test the recovery path with someone who is not the person who designed it.
