title: How secure is storing data with localStorage?
body: <p>My app requires login, and I have a <code>Remember username and password</code> ability. The username and password is then stored with </p>
  
  <blockquote>
    <p>localStorage.setItem('username', username);</p>
  </blockquote>
  
  <p>How secure is this way of storing the username and password? What I'm worried about, specially on Android, is if other apps have access to the data and can fetch the login info.</p>
  
  <p>The app is for iOs and Android, and I'm using <code>PhoneGap 2.9</code>.</p>
