Thanks, Howard, for the clarification. 
Normally, that is if I don´t forget, I log out at the end of each session.
I guess it´s a habit of mine which I have grown accustomed to.
Of course it´s (a bit) more work to request new login credentials on an almost daily basis.
It´s just how I do it. 
Thanks again and many greetings from Rosika
