After a data breach
When a stolen password list is cracked privately
—
A good website will scramble your password into an unrecognizable format. Data breach hackers can use word-scrambling tools to try to guess these scrambled passwords. The only thing protecting your password from a hacker is the number of guesses they have to try. The greater the number of possible letter combinations, the more guesses they have to make, and the longer it takes to crack.
