What is a PIN code?

A PIN (Personal Identification Number) is a numeric password used to authenticate users in various security systems. Originally developed for ATM machines in the 1960s, PINs are now ubiquitous in electronic devices, access control systems, and digital services. They typically consist of 4-6 digits, though some systems support longer codes for enhanced security.
