Answer:
Use a random selection of numbers
Explanation:
Thi is because PIN (personal identification number) is a personal but secret code associated with ATM card, that is used in protecting the privacy of individuals' accounts and allows the particular individuals to access them.
However, to have a maximum protection against anyone else being able to find out what the PIN is, the numbers should not consist numbers that are easily associated with the person choosing the PIN, for example birth date, telephone number, or street number address, as these can easily be guessed by hackers.
