🔧 Lab 14 — Your Personal Security Audit

Goal: not a simulation this time. By the end of this lab, your real accounts will be genuinely harder to break into than they were an hour ago. Work through the checkboxes in order — each one closes a door from the lesson.

Time: 60–90 minutes. Item 5 can run overnight.

Print this page or keep it open, and tick the boxes as you go:


🔍 Step 1 — Have you been in a breach?

  1. Go to haveibeenpwned.com.
  2. Type your email address and press the button.

Wait — is it safe to type my email into a random site? Fair question; you’ve been paying attention. This one, yes: it’s a famous, long-running free service made by a respected security professional, is recommended by governments and password-manager companies, and asks only for your email address — a thing that’s already semi-public (everyone you’ve ever emailed has it). It never asks for a password. The general rule stands — be suspicious — and this is a vetted exception.

  1. Read your results. Each entry is a company that suffered a breach while holding your data, with a list of what leaked.

✅ What you should see: most email addresses that have lived a few years appear in several breaches — the average is well above zero, so don’t panic. Act: for every breached site where you still remember the password — and especially if you reused it anywhere — that password’s turn comes in Step 3. If it guarded your email or bank, fix it today, first.

🔑 Step 2 — Turn on 2FA where it hurts most

Protect your single most important account first. For most people that’s their email — because “reset password” links for everything else land there. Google steps below; other providers are near-identical.

  1. Go to your Google Account (myaccount.google.com) → Security.
  2. Find 2-Step Verification and click Turn on.
  3. Follow the prompts — you’ll confirm your phone. Prefer the authenticator app or the “prompt on your phone” option over SMS if offered (the lesson’s one-line reason: phone numbers can be hijacked; apps can’t be, from afar).
  4. Save the backup codes it offers you — print them or write them down, and store them where you keep passports. They’re your spare key if the phone is lost.

âś… What you should see: logging in on a new device now demands your password and your phone. A password thief on another continent now holds half a key.

🗄️ Step 3 — The vault (or at least the three big doors)

Preferred: set up a password manager.

  1. Pick one: your browser’s built-in manager (already on your device, free, fine) or a dedicated app — Bitwarden is a well-regarded free option; 1Password is a popular paid one.
  2. Create your master passphrase using the lesson’s rule — length beats cleverness: four or more random common words, like staple garden thunder biscuit. Write it down on paper and store it with your passports until it’s memorized. (Paper at home beats weak-but-memorable — burglars trying a billion passwords per second aren’t in your kitchen drawer.)
  3. Change your three most important passwords — email, bank, main social — letting the manager generate long random ones. You’ll never type them; the vault fills them in.

Minimum version (no manager today): change those same three passwords by hand to long passphrases — four random words each, a different four for each account. Reuse is the killer; three doors, three different keys.

✅ What you should see: your three most valuable accounts now have long, unique keys — and if you chose the manager, adding every other account is now a when-you-touch-it habit, not a project.

🎣 Step 4 — Can you spot the fake bank branch?

  1. Go to phishingquiz.withgoogle.com — a free quiz by Google that shows you realistic emails, some genuine, some phishing. (Use a made-up name and email when it asks — it’s for the examples.)
  2. For each message, decide: legitimate or phishing? Use the lesson’s three tells — urgency, links (hover or long-press to reveal the true address), sender (almost-right is wrong).
  3. Read every explanation, especially for the ones you get wrong — those are the exact tricks currently in the wild.

✅ What you should see: most people miss at least one — the fakes are good. The takeaway habit beats any score: never log in through a link that came to you. Go to the site yourself, every time.

🩹 Step 5 — Update everything night

The lesson’s point made real: patches fix holes that burglars already have the memo about. Tonight:

  1. Phone: Settings → check for system updates → install. Then update all apps (App Store / Play Store → update all). Turn ON automatic updates while you’re there.
  2. Computer: Windows Update / Software Update (Mac) → install everything → restart — actually restart, tonight, not “later”.
  3. Browser: menu → Help/About → it updates as the page opens.
  4. The forgotten one: your router. If Lab 13’s safari found a firmware-update button on the admin page, run it — routers are the most neglected devices in the house.

âś… What you should see: every device restarted, zero pending updates, automatic updates on. Every published hole in your home: patched.


🎉 Done — and this one actually counts

Look at your checklist: breach awareness, a second lock on the most important door, long unique keys, trained phishing eyes, and zero known-broken locks. That is genuinely more than most people ever do, and you understood the why of every step. One suggestion: put a yearly reminder in your calendar to re-run this lab — security is a habit, not an event. Then, on to the quiz.
