Why this lesson is about laziness
Security advice usually fails not because people don’t understand it, but because it’s too much work. So you won’t find “invent a 16-character password for every website” here. You’ll find three things that, once done, let you stay lazy with a clear conscience.
The bad news about your password
If your password is a word, a name, a date of birth or a year with an exclamation mark, a program guesses it in seconds. Not because it’s clever, but because it has a list of every popular pattern. “Summer2026!” is on that list — and so is its Lithuanian twin, “Vasara2026!”.
And nobody even has to target you personally. The program tries the same popular password on thousands of accounts in a row — this is called password spraying. It only takes one person in the company using “Summer2026!” to open the door to the whole company’s email.
A passphrase instead of a password
Four unrelated words are both longer and easier to remember:
green-horse-eats-concrete. It’s a long password, but to you it’s a picture in
your head. It’s the only password you’ll need to remember at all (see the next step).
A password manager does the rest
One strong password unlocks the manager, and the manager invents and remembers all the others — a different one for every website. You no longer have to think them up, remember them or write them on a sticky note.
There are several free and reliable options; if your company uses M365, the browser’s password manager with your work account is often enough. What matters most is that passwords aren’t reused.
Why reusing a password is the most dangerous habit
When a website’s data leaks, scammers immediately try the same email and password on banks, Facebook and work email. This is called credential stuffing, and it’s a fully automated process.
One reused password turns one leak into ten problems.
MFA — the most important step in this lesson
MFA (multi-factor authentication) means a password alone isn’t enough: you also need a code from your phone. Even if a scammer has your password, they’re stuck.
If you do just one thing from this whole lesson — switch on MFA for your work email.
Not all MFA is equal
- Passkey — logging in by unlocking your phone or computer (fingerprint, face, PIN). As resistant as a hardware key, but nothing to carry around.
- Hardware key — the safest, but you need to have it with you.
- An app on your phone (Microsoft/Google Authenticator) — a good balance.
- SMS code — the weakest option, because a number can be hijacked, but still incomparably better than nothing.
What each one stops — in one table:
What each MFA method stops
| Method | Stolen password | SIM swap | Fake page (AiTM) | Notification bombing |
|---|---|---|---|---|
| SMS code | ✓ | ✗ | ✗ | ✓ |
| App code | ✓ | ✓ | ✗ | ✓ |
| Approve in the app | ✓ | ✓ | ✗ | ✗ |
| Passkey / hardware key | ✓ | ✓ | ✓ | ✓ |
MFA fatigue — a new scammers’ trick
Sigitas the scammer (our recurring villain — Sigitas is a common Lithuanian first name) has your password but not your phone. So he keeps pressing “log in” until ten approval requests arrive on your phone — often at night. The maths is simple: someone, somewhere, will tap “yes” just to make it stop.
The rule: an approval request you weren’t expecting always means “no” — and then you change your password.
Switch on MFA in half an hour — AI leads, you tap
Here the AI won’t do the work for you — and that’s how it should be. It can’t scan a QR code with your phone, and it must never see your passwords or codes. But everything else — where to start, what to switch on, which menu item on your phone — is its job. You just tap.
Copy this, fill in the square brackets and paste it into an AI:
You are my security assistant. Help me protect my most important accounts in
half an hour: switch on MFA or a passkey where it's needed most.
ABOUT ME
- Phone: [iPhone / Android]
- Work email: [Microsoft 365 / Google Workspace / other]
- Most important accounts: [e.g. work email, bank, Google, Facebook,
accounting software]
- Password manager: [which one I use / none]
PROCESS
1. ASK. Ask me the missing questions, one at a time.
2. PLAN. Rank my accounts by importance: money and email first.
Next to each, say what's best to switch on: a passkey, an app, or at least SMS.
3. DO IT TOGETHER. Guide me through one account at a time: short steps for my
phone. Wait until I write "done", then move on to the next account.
GOAL
The job is finished when every account on the list has MFA or a passkey switched
on, and the backup codes are saved somewhere safe.
STRICT RULES
- Never ask for my passwords, MFA codes or backup codes. If I write one by
accident, warn me and tell me to change it straight away.
- Don't invent passwords for me — the password manager does that.
- If you don't know the exact menu name on my phone, say you don't know and
explain what to look for.
- Answer in English.
AT THE END
A list: where MFA is on, where it isn't, and separately — WHAT YOU DID NOT CHECK.
🤖 AI route recommended
AI sets the order, you tap
With the prompt above, the AI first asks what you use, then ranks your accounts and guides you through each one separately — with menu names for your phone.
“Start with my work email. When we've finished it, tell me which account is next and why.”
Your job: scan the QR code, confirm with your fingerprint or face, and write “done”. Codes and passwords never appear in the chat.
✋ Manual route
Work email without AI
- Microsoft 365: open
mysignins.microsoft.com/security-info→ Add sign-in method → Microsoft Authenticator. - On your phone, install Microsoft Authenticator → + → work account → scan the QR code from your computer screen.
- Google:
myaccount.google.com/security→ 2-Step Verification, and where offered — Passkeys.
What never to tell an AI
AI chats are stored — both in your account and on the provider’s servers. So these things never go into a chat, not even “just to check”:
- Passwords and passphrases. Not even to find out whether they’re strong enough.
- MFA codes and backup (recovery) codes. They are the keys to your accounts.
- A password manager export. One file with all your passwords.
- “Invent a password for me.” It stays in the chat history. Passwords come from the manager.
And one more boundary: an AI agent controlling your browser must never type a password for you. It has to ask you to log in.
Pasted a password or code by accident? Don’t panic — change it now, not “later”. Then delete that chat.
For managers: MFA for everyone in a week
One person’s MFA protects one mailbox. A scammer only needs one unprotected one — so MFA has to be on for everyone. AI will prepare the plan and the email to staff.
🤖 AI route recommended
A plan and an email to the team
“I run a company of [12] people and we use [Microsoft 365]. I want MFA switched on for everyone within a week. Write a one-week plan and a short email to staff: why we're doing it, by when, who will help, and what to do if you lose your phone. First ask me what's missing, one question at a time. Then show me a draft.”
Your job: check the dates and contacts in the email and send it yourself. The “what if I lose my phone” question matters most — without an answer to it, people will be afraid of MFA.
✋ Manual route
For the admin: one switch
entra.microsoft.com→ Entra ID (Identity) → Overview → Properties.- Manage security defaults → Enabled → Save.
- Staff will be asked to register for MFA when they sign in. It's free.
If the company already uses Conditional Access rules, this isn't the right route — talk to IT.
One warning before you switch it on: security defaults turn off the old sign-in method that printers, scanners and old software often use to send email. First check what in your office sends email on its own — otherwise one morning “scan to email will stop working”.
What to do today
- Copy the prompt from the section “Switch on MFA in half an hour” and switch on MFA for your work email — AI guides, you tap. No permissions? Ask IT or us.
- Come up with one passphrase for your password manager — yourself, not with AI.
- Change reused passwords, at least wherever there’s money or email.
