Interesting problem. I had no idea that calling hide() on a QDialog 
would trigger the exit of its eventloop...

Wouldn't it make sense to separate your logic a bit? You could have your 
dialog just be the UI for entering the credentials. Another class could 
be responsible for checking them. That way, you can have that 
credentials class pop up the dialog for entering the credentials as 
often as you need. You can have all logic having to do with the status 
of the login in that single credentials class, including stuff like 
caching, timeout, etc.
