can I use Recaptcha in SB without needing PHP?

[skinkairewalker]

Hello guys, is there any way to use Google REcaptcha with SB?

I suspect that this does not work without a server language (PHP, ASP, ...) because every visitor of your site can see (and manipulate) your JavaScript code.

you can use other "captcha" using only client side scripting e.g. -> https://codepen.io/jena_96/pen/NWqPgQw
but as said using client side only reduces a LOT security level

however recaptcha is simple javascript according to its manual
https://developers.google.com/recaptcha/docs/display

so i see no reason why it can not be integrated
