Make Input Type="Password" Use Number Pad on Mobile Devices

The straightforward ways like using "pattern" and "inputmode" not working in Android nor IOS, so I emplemented the below workaround using CSS, and JavaScript.

HTML

 <div>
  <input type="password" class="form-control ng-valid-minlength ng-valid-pattern ng-dirty ng-valid ng-valid-required" id="pass" name="pass" data-ng-minlength="4" maxlength="4"  tabindex="-1">
  <input type="tel" class="form-control ng-valid-minlength ng-dirty ng-valid ng-valid-required" id="passReal" name="passReal" required="" data-ng-minlength="4" maxlength="4" data-display-error-onblur="" data-number-mask="telephone"
         tabindex="5">
</div>

JavaScript

$().ready(function(){
var xTriggered = 0;
$( "#passReal" ).keyup(function( event ) {
  $('#pass').val($('#passReal').val());
  console.log( event );
});
$( "#pass" ).focus(function() {
  $('#passReal').focus();
});

  });

Style:

input#passReal{
  width:1px;
  height:10px;
}
input#pass {
    position: absolute;
left:0px;
}

Finally, I found an answer here:

input[type=number] {
    -webkit-text-security: disc;
}

(only works in WebKit based browsers)

Some browsers (iOS) recognize the specific pattern attribute value of [0-9]* as triggering numeric keypad.

The HTML 5.1 draft contains the inputmode attribute, which has been designed to address the specific issue of input mode (like key pad) selection, but it has not been implemented yet.

You could use it for the future, though – even though the current HTML 5.1 does not allow it for type=password, for some odd reason.

<input type="password" pattern="[0-9]*" inputmode="numeric">
