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