#2DataGenetics did a similar analysis with four-digit numbers in leaked passwords and PINs. The article contains lots of cool visualizations.

#3Looks like a few of the patterns in his analysis has a tendency towards Benford's Law[1]

DataGenetics have really cool and interesting articles. I've been following them for a couple of years now...been asking for a "Bin and Order Packin" post.

Technically it describes none of these. Benford's Law only describes collections of leading digits. The charts in the article are just exponential distributions.

The article says:

> Where numbers are influenced by human thought: e.g. prices set by psychological thresholds

#7There's a comment there [0] asking for more graphs including the distribution for password managers that randomly generate passwords... erm...

#8Huh. Of all my old blog posts, this is the last one I expected to randomly resurface at the top of Hacker News.
There were a lot of other articles made using this 10M Password dataset at the time it was originally released, which the dataset author aggregated into a subreddit (https://www.reddit.com/r/10millionpasswords/). WPEngine, for example, has a much more comprehensive writeup with ad-hoc looks at specific passwords (http://wpengine.com/unmasked/).

I'm always struck by the uncredited similarities of stuff there to other sources, like the pin grid, found in this paper published earlier in 2012 than the blag there:

#10I'm surprised 69 is third instead of first. I'm even more surprised the author is surprised it's in the tops.
When I first looked at a password database I actually laughed out loud at how many 69 there were. I don't know, there is something funny about 'Yaris69' or 'Puppy69', although it's probably used ironically these days.
