Is it safe if I use the same Google Recaptcha site key and secret key on 2 different servers?

I have 2 servers, staging server and production server. Server staging is used for testing my website. While the production server is for live website

Now I use the same site key and secret key for my website on both servers

Do I need to create different site keys and secret keys of google recaptcha for the two servers? Or it does not need to be done?
