 <!-- TODO(crbug.com/603217): Use i18n instead of string literals. Figure out
                              what i18n to use for keypad, ie, does 1 ABC make
                              sense in every scenario? -->

The error message also needs to be customizable. Instead of enableError, just
have an errorMessage property.

[jdufault, 2016/08/08 23:47:25]

Use a <dom-if> instead of the error class.

<template is="dom-if" if="[[enableError]]">
  <!-- ... -->
</template>

[sammiequon, 2016/08/11 01:03:06]

Done.

[sammiequon, 2016/08/11 01:03:07]

Added a public function in pin_keyboard.js which can change this.

+          Pin or password incorrect.

[jdufault, 2016/08/08 23:47:25]

Make sure to localize any strings you include.

[sammiequon, 2016/08/11 01:03:06]

Done.
