The researchers also noted a sharp rise in region-specific weak passwords such as “India@123”, which emerged as one of the most frequently used in India.
The report said nearly one-quarter of the top 1,000 passwords consisted only of numerical strings, while 38.6% contained the sequence “123”.
Another 2% included “321”, and 3.1% contained the letters “abc”.
Security experts warn that such passwords are highly vulnerable to automated cracking tools.
They advise using unique passwords of at least 12 characters that combine upper- and lower-case letters, numbers and symbols, and enabling two-factor authentication to reduce the risk of account breaches.
