In January 2019, the largest dump of login data – now known as Collection #1 - #5, was released into the dark web.

The size of each letter indicates the frequency in which this character appears in the list of passwords. Lower-case letters at the top is what we expect to see.
We limited the dataset for our visualizations to 3-letter passwords and up to 31-letter passwords.
The saturation of color represents how frequently a feature appears.
Most sites advise people to create a password containing at least one capital letter.
The heat map of passwords that contain numbers is a near opposite of the previous one showing the positioning of lower case letters.
Add excitement to your password with an ! at the end! Or you can always ca$h in on the possibilities that special characters offer you.
