Overview
This module adds Google reCAPTCHA verification to the signup form thus preventing form spamming.
How it works
Create a reCAPTCHA key on Google Cloud console and copy the key ID and secret to Odoo as system parameters named 'gsk.recaptcha.key' and 'gsk.recaptcha.secret' respectively.
Open the signup form and you should see the reCAPTCHA widget. Your signup form is now protected.
