Following the instructions from Google, I added the approproate scripts in my index.html file :
Paste this snippet before the closing </head> tag on your HTML template:
<script src='https://www.google.com/recaptcha/api.js'></script>
Paste this snippet at the end of the <form> where you want the reCAPTCHA widget to appear:
<div class="g-recaptcha" data-sitekey="MY_KEY"></div>
The reCAPTCHA documentation site describes more details and advanced configurations.
There is no capatcha though. It is just blank. Is installing reCaptcha the same as it would be with a website? Are there any steps how to add reCaptacha into Ionic as I couldn't not find anything?
