Protected Pages with Forms Question

Hi,

I am restricting access to logged in users to pages that contain surveys (created with WPForms). The login page is protected with reCaptcha.

MY QUESTION:
If the login is protected and I’ve used Content Control to restrict access to logged in users only, is there any need to add reCaptcha to forms on that page?

My preference is NOT to use reCaptcha as it seems unnecessary and just adds a potential block to what theoretically should be a safe page.

However, if bots can somehow find the form without accessing the page then I will need to use reCaptcha.

Thanks,
Fez
