Build a layered defense
Four habits.
A much smaller risk.
A strong password is one layer—not the whole defense. Combine these habits to protect every account.
Make it long
Aim for at least 15 characters when a password is the only authentication factor.
Make it unique
Never reuse a password. One breached service should not expose your other accounts.
Use a manager
Let a password manager generate and remember random passwords for you.
Add another factor
Use MFA or passkeys so a stolen password alone is not enough.
