Setting recaptcha in a different language other than english

Question

Is it me or is recaptcha images cannot be translated to another language other than EN? I have and it is still in English. Is this intentional?

Answer 1

replace lang to hl and it'll work:

<script type="text/javascript">
var recaptcha1;
var myCallBack = function() {
    //Render the recaptcha1 on the element with ID "recaptcha1"
    recaptcha1 = grecaptcha.render('recaptcha1', {
        'sitekey': '6LdJLws_your site key',
        'hl' : 'fr'
    });
};
</script>

Answer 2

For reCAPTCHA 2. Since a while have passed

This is your link to cdn look at the end, hl parameter

<script src="https://www.google.com/recaptcha/api.js?onload=myCallBack&render=explicit&hl=fr" async defer></script>

This is your captcha inside the form

<div id="recaptcha1"></div>

This is your javascript you can specify the lang code here too, I assume one of them is enough

var recaptcha1;
var myCallBack = function() {
    //Render the recaptcha1 on the element with ID "recaptcha1"
    recaptcha1 = grecaptcha.render('recaptcha1', {
    'sitekey': '6LdJLws_your site key',
    'lang' : 'fr'
   });};

You can add multiple reCAPTCHAs with this method.
