title: How do I reset a PasswordChar?
body: <p>I want to make my PasswordChar in a box empty when a user clicks a button (so they can confirm they wrote it right, it's easier than having to type it twice)</p>
  
  <p>However, when I do:</p>
  
  <blockquote>
    <p>password.PasswordChar = null;</p>
  </blockquote>
  
  <p>It says</p>
  
  <pre><code>Cannot convert null to 'char' because it is a non-nullable value type
  </code></pre>
  
  <p>Setting it to '' says it's an empty char, and ' ' just makes it a space. What do I do?</p>
