I took a sample of 34k. I may have had some files that didn't download fully[1]. I was only interested in picking out some trends.

66 - No password (ie null)

580 - had the password "315475"

492 - had password "123456"

187 - had password "123456789"

68 - had password "102030"

62 - had password "123"

52 - had password "12345"

44 - had password "1234"

29 - had password "101010"

35% were numeric/number only passwords. There were many that were a variation of 123...

The rest appear to be a mixture but first names are popular. I haven't tried, but would assume many of these would be the same passwords for the registered email (username).

The day someone comes up with an alternative to passwords it will be a great day!

Edit: [1] 34k unique accounts, I must have deleted duplicate usernames/accounts.
