Caliburn.Micro support for PasswordBox?

Question

The Caliburn.Micro home page at http://caliburnmicro.com makes the below claim but I am unable to make CM work with a PasswordBox control using any variation I can think of

Answer 1

The solutions provided here seem to be needlessly complicated.

We can very easily use Caliburn.Micro actions to send our password to the ViewModel.

XAML:

ViewModel:

public void OnPasswordChanged(PasswordBox source)
{
    password = source.Password;
}

Then remember to clear the password fields so they don't remain in memory.

NOTE: Obviously this solution doesn't allow you to easily change the password from the ViewModel, if that is necessary, then it's probably best to go with the attached property approach.
