I have been looking into how to implement a captcha in the forms of a website. Specifically, I used Google ReCaptcha using the API provided by it. All this I did in a single Wordpress theme and I must pass those changes to a new theme.
To avoid this I was asked to use a plugin so that it does not affect when you decide to change to another topic.
The problem is that the only ones I have found are for the sale of login to the wordpress dashboard and for comments on the users' posts, none for forms.
Does anyone know the name or implemented something similar?
