Currently GF only works with the very old now form of Google Recaptcha which is not good for accessibility - I am blind myself and lots of our site users are vision impaired.
Google now has V3 of Recaptcha which normally requires no input from the visitor and returns a value between 0 and 1 depending on the likelihood of the visitor being a bot. Hence any integration needs to let the site admin set their tolerance level and decide what to do if doesn’t pass - reject, forward on to more traditional captcha etc.

There is a Google recaptcha plugin by BestWebSoft that has a free and premium version that works with all forms of Google Recaptcha including the invisible recaptcha and this latest V3 but they don’t currently support Gravity Forms protection.

I am wondering if GF might be able to create an official addon to support this latest far more accessible version of recaptcha - not only would it help me out but it would help improve accessibility on thousands of sites that use GF if you could then encourage them to swap from the current recaptcha to this more friendly version.
Or if someone else can create a GF addon to make this third party plugin using V3 work with GF.
