When the VisualCron client is started, an initial login (to server) window is opened. You need to login because the server may be accessed also from other computers. If you haven't defined any connection, VisualCron will use the default server login parameters.

For security reasons, you should change user name and password after the initial login in the main menu Server > Main settings > User permissions dialog.

If you want to add new connections, for example to other computers, you select the main menu File > Servers > Manage servers option. See manage servers for more information.
