title: AWS Cognito Identity NotAuthorizedException
body: <p>I'm using the AWS javascript sdk in order to integrate user pools with a web app that I am building. The user pool is setup and I've followed the usage example here: <a href="https://github.com/aws/amazon-cognito-identity-js" rel="nofollow">https://github.com/aws/amazon-cognito-identity-js</a></p>
  
  <p>I keep getting an error that says:
  "NotAuthorizedException: Unable to verify secret hash for client (my app client id)"</p>
  
  <pre><code>AWS.config.region = 'us-east-1'; // Region
  AWS.config.credentials = new AWS.CognitoIdentityCredentials({
      IdentityPoolId: '...' // my identity pool id here
  });
  
  
  AWSCognito.config.region = 'us-east-1';
  AWSCognito.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId: '...' // my identity pool id here
  })
  
  
  var poolData = {
    UserPoolId: '...', // my user pool id here
    ClientId: '...'  // client id here
  };
  var userPool = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserPool(poolData);
  
  var userData = {
      Username : 'username',
      Pool : userPool
  };
  
        var attributeList = [];
  
        var dataEmail = {
            Name : 'email',
            Value : 'email@mydomain.com'
        };
        var dataPhoneNumber = {
            Name : 'phone_number',
            Value : '+15555555555'
        };
        var attributeEmail = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserAttribute(dataEmail);
        var attributePhoneNumber = new AWSCognito.CognitoIdentityServiceProvider.CognitoUserAttribute(dataPhoneNumber);
  
        attributeList.push(attributeEmail);
        attributeList.push(attributePhoneNumber);
  
        userPool.signUp('username', 'password', attributeList, null, function(err, result){
            if (err) {
                alert(err);
                return;
            }
            cognitoUser = result.user;
            console.log('user name is ' + cognitoUser.getUsername());
        });
