Parental Control Password
I'm on El Capitan 10.11.3 and in attempting to add some parental security controls, I've set up a password which I cannot now access (Forgotten or incorrectly submitted)
Parental controls is now restricting access to MS Word and Excel sites and I now can't use them. I know my User name and password, I know my apple id and password, surely there must be a simple way of changing my parental control password. This issue seems to be not being able to get into administrator's name and password when I try to unlock the padlock in either Users and Groups or Parental Controls.
Any advice gratefully received!
iMac, OS X El Capitan (10.11.3)
