Somewhere along the way, “use a strong password” became the security advice everyone knows by heart.
Twelve characters. A symbol. Maybe a passphrase involving your childhood dog.
It is good advice.
It is just not the layer that stops many modern account takeovers.
The habit that matters more is this:
Turn on multifactor authentication, especially for the accounts that control everything else.
A strong password protects you against someone guessing your login. But many account breaches do not begin with guessing. They begin with a password that was stolen somewhere else.
A data breach leaks millions of email and password combinations. Those combinations get quietly tested across email accounts, banking sites, shopping accounts, social platforms, and work tools.
This is called credential stuffing, and it does not care how clever your password was. If you reused it somewhere, it may already be exposed.
Multifactor authentication, often called MFA or two-factor authentication, adds another layer. Even if someone has your password, they still need something else: a code from an app, a tap on your phone, a passkey, or a physical security key.
A quick note: not all MFA is equal.
Text message codes are better than nothing, but they are the weakest option because phone numbers can be hijacked through SIM swapping.
Authenticator apps are stronger.
Passkeys and physical security keys are stronger still, because they are designed to resist phishing in a way ordinary codes do not.
You do not need the strongest option on every single account.
Start with the accounts that matter most:
- Your primary email
- Your banking and financial accounts
- Your password manager
- Your cloud storage
- Your business or work accounts
- Any account used to reset other accounts
Your email should come first because it is usually the master key. Most password reset links go straight there.
Then move to banking.
Then work accounts.
Then social media and shopping accounts.
Most platforms hide this setting under “Security,” “Login,” “Two-Factor Authentication,” or “Multifactor Authentication.”
This is not glamorous advice. It will not make headlines. But it is often the difference between a leaked password being a warning sign and a leaked password becoming someone else’s way into your life.
Strong passwords still matter.
But they should not be standing there alone.
