Protect Your Accounts

Strong passwords + MFA = a much harder target

The single biggest upgrade you can make to your digital security is unique passwords for every account, plus multi-factor authentication on the important ones.

Use a password manager

Built-in managers (iCloud Keychain, Google Password Manager, Windows/Edge) generate and store unique strong passwords so you never reuse one.

  • Never reuse a password across services.
  • Let your password manager generate them.
  • Lock your device + manager with MFA.

Turn on multi-factor authentication

MFA adds a second factor (an app code, a hardware key) so a stolen password alone isn't enough.

  • Prefer an authenticator app over SMS codes.
  • Save backup codes in a safe place.
  • Keep recovery email & phone up to date.
