Q: reset the testriction code

Hi pankajfromzira,

Thank you for visiting Apple Support Communities.

Do you need to recover the Restrictions (parental controls) passcode on your iPhone?

If you can't enter the passcode, About Restrictions (parental controls) on your iPhone, iPad, and iPod touch says that the device needs to be erased:

If you lose or forget your Restrictions passcode, you'll need to erase your device and then set it up as a new device to remove the Restrictions passcode. Restoring the device using a backup won't remove the passcode.

Sincerely.
