Password Settings Menu
The Password Settings menu lets you change the Gateway’s default administrator
username and password and the user’s password.
The Password Settings menu also lets you change the number of minutes of inactivity that
can occur before your Web management session times out automatically. The default
setting is 10 minutes.
In addition, you can configure Remote Authentication Dial In User Service (RADIUS),
Terminal Access Controller Access-Control System Plus (TACACS+) , and Terminal Access
Controller Access-Control System (TACACS) configuration settings.
y RADIUS is a networking protocol that provides centralized authentication, authorization,
and accounting management for computers to connect and use a network service

authentication server commonly used in UNIX networks. TACACS lets a remote access
server communicate with an authentication server determine whether the user has
access to the network.

and other networked computing devices via one or more centralized servers. TACACS+
provides separate authentication, authorization, and accounting services.
To access the Password Settings menu, click System in the menu bar and then click the
