How did you "avoid" sample bias? How many of the passwords come from databases that were dumped in cleartext or cracked with 100% success? Meaning every account on that system was included in cleartext or 100% of the passwords from a dump were cracked. The reason I ask is that the dataset you analyzed does not make this claim: "Now not all of these passwords are plaintext. Many dumps include passwords in a hashed format that requires you to crack them yourself." https://xato.net/a-glimpse-into-the-world-of-internet-password-dumps-5ee4609da237 https://xato.net/a-glimpse-into-the-world-of-internet-passwo...
