<p>A while ago, arc90 decided that having to submit a form to find out if you’ve entered the right password was inefficient, so they set about finding a quick and secure way of telling you if the password you’ve entered is correct. They came up with <a href="http://lab.arc90.com/2009/07/hashmask.php" rel="nofollow ugc">Hashmask</a> which does that pretty well.</p>
<p>When you enter your password into the field, you’ll be shown a little graphic. Remember that graphic! That’s the visual representation of your password. For instance, if I enter my password I see a green shape, with two peaks at the beginning. If I type it in, and that’s not the graphic I see then I’ve typed it wrong and know to type it again (without wasting time submitting the page)!</p>
<p>It’s completely secure though. Even if someone sees what shape your password makes, there’s nothing that can do to convert that image back to a real word.</p>

XO Security

This is awesome plugin!
It has all the features I need and is very easy to use.

Awesome!

長年、SiteGuardを使っていましたが、たまにログインできなくなってプラグインをサーバーから削除とかしたりだったので、こちらのプラグインを使い始めました。
設定画面もわかりやすく、作動も安定していて、ログイン試行履歴とかも見れます（結構不正ログインされようとしているのがわかって楽しい）、随時他のサイトのセキュリティプラグインもこちらに切り替えていこうと思っています。感謝感謝
