Nicole Accounts do not have PIN codes, only cards have PIN codes. Your bunq user account has a 6-digit security code for login. And each of your cards has a 4-digit PIN code for payment and withdrawals. You can use the same PIN code for all of your cards or you can set them individually to a different PIN code.
If you have forgotten the PIN code of any of your cards, just set a new one through the app: https://together.bunq.com/d/60
