Cybersecurity experts warn against predictable PIN codes
Security experts are warning users about the risks of using predictable four-digit PINs and passwords for mobile devices and banking. While a four-digit code offers 10,000 possible combinations, human behavior often results in highly predictable patterns that are easy for unauthorized users to guess.
An analysis by information security expert Nick Berry, which examined millions of four-digit passwords from leaked datasets, revealed that the combination ‘1234’ was the most frequent, appearing in over 10 percent of cases. Other highly common and insecure sequences include ‘1111’, ‘0000’, ‘1212’, and ‘4321’.
Research indicates that the 20 most popular combinations alone account for more than 25 percent of all analyzed passwords. Experts suggest that users should avoid simple sequences, repeated digits, or patterns that form geometric shapes on a keypad to improve personal data and financial security.
