A numeric password is a type of security code that consists solely of numbers. It is commonly used to protect access to accounts, devices, or sensitive information. Numeric passwords can vary in length, typically ranging from four to six digits, and are often used in combination with other security measures, such as PINs or two-factor authentication. These passwords are easy to remember but can be vulnerable to attacks if they are too simple or predictable. Users are encouraged to create unique combinations and avoid using easily guessed numbers, such as birthdays or sequential digits, to enhance their security.
