Thank you so much. I am in the same situation exactly. return null is the key
in getPasswordAgain(info). If you put a breakpoint here you can see it enters
here to ask the password again.
I think, it will also work if we implement a logic of showing a dialog to ask
the user the password again, but return null is the simpler approach.
