Passwords, MFA & Account Safety
In this lesson you will
- Create strong, unique passwords
- Turn on multi-factor authentication
Most account break-ins don't involve clever hacking — they happen because a password was weak, reused, or guessed. Getting the basics right stops the majority of real-world attacks before they start.
- Strong passwords: Use a long passphrase (e.g. "PurpleGoat$Runs42Fast") rather than a short complex one — length matters more than symbols.
- Never reuse passwords: If one site is breached, reused passwords let attackers into every other account you used it on.
- Multi-Factor Authentication (MFA): Adds a second step (a code sent to your phone, or an authenticator app) so a stolen password alone isn't enough to break in. Enable it on email, banking, and social media first.
- Password managers: Tools that generate and remember strong unique passwords for every account, so you only need to remember one master password.
Practical Skill: Audit your own accounts: identify any reused passwords, change them to unique passphrases, and enable MFA on your email account today — it's usually the account that can reset everything else.
=== PERSONAL ACCOUNT SECURITY AUDIT === [ ] Email account has a unique password (not reused anywhere)[ ] Email account has MFA/2-step verification enabled[ ] WhatsApp has two-step verification enabled (Settings -> Account -> Two-step verification)[ ] Banking/mobile money app has a unique PIN, never shared[ ] Social media accounts have MFA enabled where available[ ] No passwords are written in an unlocked phone Notes app[ ] A password manager (or a written list kept physically safe) is used instead of memorizing weak, reused passwords === PASSPHRASE VS PASSWORD === Weak: P@ss1 Better: Purple-Goat-Runs-42 Why: Longer phrases are far harder to crack, even without complex symbols, and easier for you to remember.
Practice exercise
List your five most important accounts, move them into a password manager with new generated passwords and enable MFA on your email.
Key takeaways
- Length and randomness make passwords strong
- Never reuse passwords on important accounts
- MFA stops most account takeovers
