The proxy settings window allows you to adjust the way the program connects to the Password Server. An established Internet connection is required for that, so if you access to Internet using a proxy, you should specify its settings here.
There are three available proxy options which allow you to either use IE’s proxy settings, specify your own settings, or do not use proxy at all.
Note, that only proxy Port and Address are obligatory, while User and Password are optional.
