title: How to know plain text of :encrypted_password, in devise?
body: <p>If i use has_secure_password, i have whitelist are: <code>password</code>, <code>password_confirmation</code>, and <code>password_digest</code>. With <code>password</code> is the plain text of <code>password_digest</code>, which was encrypted by bcrypt.</p>
  
  <p>But when i use devise with my user model, it has only <code>encrypted_password</code> field, I don't know how to know plain text of <code>password</code>. The schema doesn't has <code>password field</code>. I uasually use rails consle to debug. So anyone can help me how to know the plain text of <code>encrypted_password</code>.</p>
