    file_object.write(id+"\n"+pwd)
    self.PopupNotifyMessage("Saved.",self.SetIDEditLineFocus)
    file_object.close()

Answer 1

You'll want to use the python hashlib. An example could look something like this:

  import hashlib

  def valid_password(userid, password):
      user = get_user(userid)
      pw_hash = hashlib.sha256(password).hexdigest()
      if user.hash == pw_hash:
          return True
      return False

Also I recommend reviewing some password storage best practices noted in this SO

Edit: I used sh256 in this example, but that is more useful as a message digest. A better use would be hashlib.pbkdf2_hmac or another key derivation function. There is a good write up here.
