Secure PIN Generation
PINs are commonly used for ATMs, phone locks, and access control systems. Random generation ensures you avoid predictable combinations like "1234", "0000" or birthdates that attackers try first.
For better security, always choose 6-digit PINs when possible. They provide 100 times more combinations than 4-digit PINs, significantly increasing protection against brute-force guessing.
