A method to authenticate a first computer system over a network to a
second computer system is disclosed. A login user interface (UI) is
presented to a user of the first computer system while disconnected from
the second computer system. The login UI presents at least one input
field to receive login input from the user and a security indicator that
has been previously selected by the user and that is local to the first
computer system. Login input is selectively received from the user based
on a determination that the user recognizes the security indicator as
having been previously selected by the user. A connection is established
between the first computer system and the second computer system over the
network. The received user input is transmitted using the established
connection to the second computer system for authentication of the first
computer system.
