title: iOS/Android: Open numeric keyboard on password-type input field
body: <p>In my Angular/Ionic app there is a PIN number security, where the user needs to enter 3 digits in three different input fields.</p>
  
  <p>I use inputs of "password" type for that, but I'd like to show a telephone-type keyboard (with only the 10 digits) when the user taps on those inputs.</p>
  
  <p>Using <code>&lt;input type="tel"&gt;</code> is not good because I want the inputs to hide the digits like password-type inputs.</p>
  
  <p>Any idea on how to do this? Also, this needs to work on both Android/iOS platforms.</p>
  
  <p>Cheers,</p>
