As i saw some posts here on the forum that recaptcha v3 is not yet supported or something like that.
I use recaptcha v2 however i am thinking of migrating to recaptcha enterprise as it includes much more security features such as: Password leak detection, Score granularity (11 levels), Reason codes, Feedback on assessments using the Annotation API, iOS and android SDK,
and even more features that you can look at here https://cloud.google.com/recaptcha-enterprise/docs/compare-versions
I use OJS 3.3.0.5, and i want to make sure that its compatible with it before migrating, so if you have an answer, please let me know
