Two locks on the door
A password is one lock; two-factor adds a second — a code sent to your phone — so a stolen password alone won't get a thief in. Simple habits like strong, unique passwords and 2FA are what actually keep you safe online.
Defense you control
A strong password is long and unique — a short common word is guessed in seconds, while a long random passphrase would take centuries. Two-factor authentication (2FA) adds a second proof, like a code from your phone, so a stolen password alone isn't enough.
Length beats complexity
'correct-horse-battery-staple' is far stronger than 'P@ss1' — length adds far more possibilities than a few symbols do.
Lab · Rank the passwords
- Compare '123456', 'summer', and a 4-word passphrase.
- Order them weakest to strongest.
- Add 2FA to the account — what does an attacker now need?
What you should see: The passphrase wins on length. With 2FA on, a stolen password is useless without the second factor from your device.
