Good news, Memberstack's signup & login forms come standard with reCaptcha to prevent bots & spam. 🎉
We use V3 of reCaptcha. This version is invisible, so it doesn't require any action from your members. If it fails, a red error bar will appear that reads "Could not verify recaptcha." If this becomes an issue, you can disabled the feature.
How to disable reCaptcha.
Navigate to Settings in your dashboard where you'll find a toggle switch. A grey switch means reCaptcha is disabled.
Notes: Because of the invisible Google reCaptcha, users from China won't be able to sign up as China bans Google. You will need to turn off reCaptcha to allow Chinese users to sign up or log in.
