Password Reuse: One Breach Can Unlock All Your Accounts

Small businesses often underestimate the danger of reusing the same password across multiple accounts. Unfortunately, this is one of the easiest ways hackers break into business systems.

Why Password Reuse Is Dangerous

When one account is breached in a data leak, attackers use those stolen credentials in “credential stuffing” attacks — testing them across other accounts and services. If your email password matches your payroll system password, you’ve just given them the keys to everything.

How to Stay Safe

✅ Use unique passwords for each account.
✅ Adopt a password manager to keep things secure.
✅ Require employees to use strong passphrases (12+ characters).
✅ Enable Multi-Factor Authentication (MFA).

Your weakest password shouldn’t be the reason your business is compromised.
