Wish it was so easy, some websites have decided they like lower security, especially for some reason, my banks. Banc Sabadell in Spain for example, only does 2FA via SMS (famously insecure) and your password is limited to 6 numbers, and accepts nothing else.
This thread isn't about data in general, only passwords. So first of all, a strong password is much harder to crack in the instance that it's stored in a hashed form in the database. In the instance it's stored (unforgivably) in cleartext, it cannot be used, because an additional factor is required to authenticate. That is how exactly.
