LONDON: ‘123456’ is the most widely-used password on breached accounts, a study revealed.

The study by the UK’s National Cyber Security Centre (NCSC) helped to uncover the gaps in cyber-knowledge that could leave people in danger of being exploited, the BBC reported on Sunday.

Top of the list was “123456”, appearing in more than 23 million passwords. The second-most popular string, “123456789”, was not much harder to crack, while others in the top five included “qwerty”, “password” and “1111111”.
