Is it safe to show the AWS cognito pool ID in my html? : <p>I am building a serverless website with AWS Cognito, Lambda, S3 and a dozen more of their services. My HTML/JS in my login page has the cognito pool ID. How safe is this? I know that it is best practise to hide sensitive stuff. But this is not client-server. Its all client if im honest. I do access some sensitive data via a lambda call. But even this call requires some plain-text sensitive inputs like the user ID. </p>

<pre><code>    &lt;script src="https://sdk.amazonaws.com/js/aws-sdk-2.3.7.min.js"&gt;   &lt;/script&gt;
    &lt;script&gt;
    AWS.config.region = 'XX-XXXX-1';
    AWS.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId: 'XX-XXXX-1:XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX'
    });
    var lambda = new AWS.Lambda();
    &lt;/script&gt;
</code></pre>

<p>I really dont like the poolID visible. An attacker can copy this and brute force my cognito IDs. Any ideas to hide it?</p>
