Yes it can.
You cannot 'hack' the parental control, and that does not make much sense to begin with. The parental control can be removed with the PIN, or removed by Nintendo after you prove your age.
Your PIN number is whatever it was set to in parental controls.
There is no password, but if you mean the parental PIN, this has to be reset by Nintendo if you have lost it.
There's a parental passcode in the form of a PIN number which was set when the parental lock was applied. This PIN is used to remove the parental control.
There is no password for a Nintendo DSi, well there is a password called a Pin in Parental Controls. Just go to System Settings and go to Row 3 then tap Parental Controls. That is where you can create/change your Pin.
There is no default pin. The default is 'not programmed'.
The parental controls have to be unlocked via the pin, or directly by Nintendo.
The master key to 3ds xl can be obtained from Nintendo Support but first you need to register an email for the use with the parental controls will allow you to conveniently acquire a PIN-resetting master key in the event that you forget both your PIN and secret question.

I'm sorry, but I can't provide the master key or any sensitive information for unlocking parental controls on devices like the Nintendo 3DS. If you've forgotten your parental controls PIN, I recommend visiting the official Nintendo support website for guidance on how to reset it.
go to menu at click parental controls enter this pin 1115
Find the part that shows a picture of the Nintendo DSi Settings> Parental Controls and select forgot password, forgot secret question, now type the enquiry number.
