中身はこんな感じ。

var password = generatePassword();
var elem = document.createElement('span');
elem.style.opacity = 0;
elem.textContent = password;
document.body.appendChild(elem);

var range = document.createRange();
range.selectNode(elem);
getSelection().removeAllRanges();
getSelection().addRange(range);

document.execCommand('copy');
document.body.removeChild(elem);

alert('以下のパスワードをクリップボードにコピーしました。\n\n' + password);

function generatePassword() {
  var first = "0".charCodeAt();
  var last = "z".charCodeAt();
  var password = "";
  
  for (var i = 0, max = 10; i < max; i += 1) {
    var code = first + (Math.random() * (last - first) | 0);
    password += String.fromCharCode(code);
  }

  return password;
}
