Google Recaptcha on Multisites in WordPress [closed]

I am using Multisites Where Network domain is developmentabc.wpengine.com and child sites domains are like developmentabc.wpengine.com/xyz.com , developmentabc.wpengine.com/klm.com. I have registered google recaptcha v2 for Network site domain and got secret key and site key. My question is Can i use same secret and site key for child sites? because only child site like abc.com can’t be registered for recaptcha key. Thanks in advance.
