Most common password is STILL 123456

In a recent study, Hakçıl, a Turkish student studying at a university in Cyprus, downloaded and analysed more than one billion leaked accounts and discovered that the most common password is STILL 123456. It occurred over 7 million times, or about one in every 142 passwords.

Some COOL STATS from the study include:

• From 1.000.000.000+ lines of dumps, 257.669.588 were filtered as either corrupt data(gibberish in improper format) or test accounts.
• 1 Billion credentials boil down to 168.919.919 passwords, and 393.386.953 usernames.
• Most common password is 123456. It covers roughly 0.722% of all the passwords. (Around 7 million times per billion)
• Most common 1000 passwords cover 6.607% of all the passwords.
• With most common 1 million passwords, hit-rate is at 36.28%, and with most common 10 million passwords hit rate is at 54.00%.
• Average password length is 9.4822 characters.

On a more positive note nearly 9% of the passwords are unique.
