Password Security Checklist: Lock Every Account
Most accounts are not broken into through clever hacking. They are opened with a password someone reused, guessed, or handed over in a phishing message. As a licensed security officer in Florida, I treat an online account like a door: a good lock, a second lock, and a key you do not leave lying around.
1. Start with your email
Your email is the master key: password resets for banking, shopping, and social media all flow through it. Secure email first, then banking, then social media.
2. Give every account its own long password
- Never reuse a password. If one site leaks, a reused password hands an attacker every other account that shares it.
- Make it long, not clever. A passphrase of several unrelated words is easier to remember and harder to guess than a short password.
- Use a password manager. Let it generate and store a unique password for each account, so you only have to remember one strong master password.
3. Turn on multi-factor authentication
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) urges everyone to use multi-factor authentication, noting that a password alone is not enough and a second factor makes you significantly less likely to get hacked.
- Strongest first: a hardware security key or passkey, where offered. A hardware security key is a small device you tap to prove it is really you.
- Next best: an authenticator app code.
- Still worth it: a text-message code. It is weaker than the options above, but it is far better than a password alone.
4. Save your backup codes
When you turn on multi-factor authentication, most accounts give you backup codes. Save them in your password manager or on paper kept at home — not in a phone screenshot. If you lose your phone, those codes are how you get back in.
5. Build the daily habits
- Turn on automatic updates for your phone, computer, and browser, so known flaws get patched.
- Think before you click. If a message pressures you to act fast, go to the site yourself instead of clicking its link. My Phishing Checklist: Spot the Scam in 60 Seconds walks through the signs.
- Never share a password or a login code with anyone who asks for it — no real bank or service will ask you for one.
- Change a password only with a reason: a breach notice, a suspicious login, or a password you know was reused.
The takeaway
Unique passwords, a password manager, and multi-factor authentication on the accounts that matter most — that is the whole system. Do email today, banking tomorrow, and the rest as you log in.
