My kids hit factory reset now it's asking for password and I don't kno

So sounds like it is Google Account locked. Also known as FRP (Factory Reset Protection).

Obviously the easiest way to do that would be to try and remember the Google account that was used on the device, if you cannot remember the email you can go to https://accounts.google.com/signin/v2/us... where you should be able to find out your Gmail email if you put in either a phone number or another email associated with that account.

Failing that there are plenty of ways to get past this if you just search the model number followed by FRP bypass on Google as long as you are the owner of the device.
