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.

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
