title: Why the words used in devise are not always translated...?
body: <p>in devise/sessions/new.html.erb I have this</p>
  <pre><code>&lt;%= hidden_field_tag :from, @from %&gt;
  &lt;!-- Username --&gt;
  &lt;div&gt;
      &lt;div&gt;&lt;%= f.label :username_or_email %&gt;&lt;/div&gt;
      &lt;%= f.text_field :username_or_email, autofocus: true, required: true %&gt;
  &lt;/div&gt;
  
  &lt;!-- Password --&gt;
  &lt;div&gt;
      &lt;div&gt;&lt;%= f.label :password %&gt;&lt;/div&gt;
      &lt;%= f.password_field :password, autocomplete: &quot;off&quot;, required: true %&gt;
  &lt;/div&gt;
  </code></pre>
  <p>But I have a problem with the translation. I don't know why but &quot;password&quot; word sometimes is translated (for example in Japanese) <strong>but</strong> sometimes not (for example in Chinese).</p>
  <p>(The word &quot;password&quot; is not added in my config/locales/ja.yml even in config/locales/zh.yml)</p>
  <p>While username_or_email is never translated. Why?
  Should I download <a href="https://github.com/plataformatec/devise/wiki/I18n" rel="nofollow noreferrer">those files</a>? Now it works also without them for several words (i don't know how...)</p>
