An analysis of user data from Have I Been Pwned? reveals that approximately 10% of individuals still utilize the same four-digit PINs, reflecting poor security practices stemming from human behavior. The study indicates that even with a limited number of guesses, such as five, a malicious user retains roughly a one-in-eight chance of successfully deciphering a PIN. Visualizations of commonly used PIN combinations reveal patterns that could suggest users should avoid certain sequences, as many adhere to predictable digit arrangements.
