Personal Identification Number (PIN)
Definition
A PIN is a numeric code used in the banking industry as a secure method to authenticate or authorize transactions on an electronic device.
Detailed Explanation
A Personal Identification Number (PIN) is a secure, numeric password, typically consisting of four to six digits, used to authenticate the identity of individuals attempting to access a banking system via an ATM, debit card, or other electronic banking devices.
The PIN is a critical component of maintaining the security of financial transactions, as it verifies that the person attempting to access the account is authorized to do so. For added security, it is advised that PINs be kept confidential and not written down or shared with others. Financial institutions encourage customers to regularly change their PINs and avoid using easily guessable sequences, such as birth dates or consecutive numbers.
The effectiveness of a PIN in securing accounts is based largely on the secrecy of the number; therefore, breaches often occur as a result of user behavior rather than technological failure.
Example
When Sarah goes to an ATM to withdraw money, she inserts her bank card and is prompted to enter her four-digit PIN. Once she inputs the correct PIN, she gains access to her account and can proceed with her cash withdrawal.

For security reasons, it is best to use different PINs for different accounts to reduce the risk of multiple accounts being compromised if one PIN is discovered.
How can I create a secure PIN?
