You wouldn’t hand over the office keys without checking ID; yet a single stolen password can unlock email, payroll, even bank portals. Multi‑Factor Authentication (MFA) adds one simple step—typically a phone prompt or 6‑digit code—that slams the door on 99 % of password‑based attacks, according to Microsoft’s 2025 Security Intelligence Report.
Three Facts Every Business Leader Should Know
Executives are prime targets. Phishing kits now scrape LinkedIn to auto‑send “urgent wire” messages that look like they came from you. MFA blocks the fraud even if the attacker guesses your password.
It’s fast and free. Most cloud services (Microsoft 365, QuickBooks Online, major banks) include app‑based MFA at no extra charge. Setup takes under five minutes per user.
Cyber‑insurance requires it. More than 80 % of carriers now mandate MFA on email and remote access before they’ll issue or renew a policy—and they can deny claims if it isn’t enabled.
Quick Start Checklist
| Step | What to Do | Time |
|---|---|---|
| 1. Identify critical logins | Email, banking, accounting, payroll, customer portal | 10 min |
| 2. Enable app‑based MFA | Use Microsoft/Google Authenticator or your bank’s app rather than SMS where possible | 5 min per account |
| 3. Store backup codes | Download and keep them in a locked drawer or password manager | 2 min |
| 4. Require MFA for all owners & managers | Make it policy; compliance matters more than tech | 15 min staff memo |
Bottom line: MFA costs virtually nothing, takes under half an hour to deploy on key accounts, and stops the vast majority of credential‑theft attacks. If you haven’t flipped the switch yet, there’s no easier win for security—or sleep—this month.
