Utilizing Captcha with Meteor's accounts-ui-bootstrap-3 for enhanced security

Is it possible to incorporate Captcha verification when utilizing the combo of Meteor packages accounts-ui-bootstrap-3 and accounts-password?

What is the process for integrating a package such as captchagen with accounts-ui?

Answer №1

I took the initiative to develop my own solution by directly integrating Google's Recaptcha

Here are the steps I followed:

  1. Downloaded Recaptcha .js files and placed them in the lib directory
  2. Added
    <div id="recaptchaDiv"></div>
    to my HTML page
  3. In the client code, included the following snippet:


Template.YOUR_TEMPLATE.rendered = function () {
  Recaptcha.create("YOUR_RECAPTCHA_KEY",
    "recaptchaDiv",
    {
      theme: "red",
      callback: Recaptcha.focus_response_field
    }
  );
};

Implemented a server-side method as follows:

validateCaptcha: function(challenge, resp){
  var self = this;
  var ip = self.connection.clientAddress;
  var result = HTTP.post('http://www.google.com/recaptcha/api/verify', {params: {
    privatekey:"YOUR_PRIVATE_KEY",
    remoteip:ip,
    challenge:challenge,
    response:resp,
  }});

  if(result.statusCode === 200){
    if(result.content==="true\nsuccess")
      return "success";

    return "fail";
  }
}

Then, during form validation, invoke this method:

Meteor.call("validateCaptcha",Recaptcha.get_challenge(),Recaptcha.get_response(),function(res){
        if(res=="ok"){
          console.log("it works")
        }else{
          Recaptcha.reload();
          console.log("wrong captacha")
        }
      });

You may need to make some adjustments in the package itself to integrate it with accounts-ui
