MainBoss's Web Access continually ask for passwords
If you are operating your browser in private mode it will ask for you password each time. That is to be expected since no history is supposed to be saved in private mode.
Some browsers will start in private mode if they were last used in private mode, and you may be using private mode unexpectedly, and thus be asked for passwords over and over again.
To fix the problem make sure that you are not in private mode.
