ClientPIN
ClientPIN is a security feature used in some software applications and online services to protect user accounts. It typically refers to a personally identifiable number that a user establishes and associates with their account for an additional layer of authentication. Unlike a password, which can be a combination of letters, numbers, and symbols, a PIN is usually a shorter, numeric code, often four to six digits long. The purpose of a ClientPIN is to prevent unauthorized access to sensitive information or functionalities even if a password has been compromised. It is commonly used for high-risk transactions or when accessing critical account settings. Users are generally prompted to enter their ClientPIN after successfully logging in with their primary credentials, or in specific scenarios where extra verification is deemed necessary by the service provider. The security of a ClientPIN relies on the user choosing a number that is not easily guessable, such as sequential digits or birthdates.
