Password Settings
Use this menu to restrict access based on a password. By
default, there is no password. For security you should assign one
before exposing the Router to the Internet.
Passwords can contain from 3–12 alphanumeric characters and
are not case sensitive.
Note: If your password is lost, or you cannot gain access to
the user interface, press the Reset button on the rear
panel (holding it down for at least five seconds) to
restore the factory defaults. (The default is no
password.)
Enter a maximum Idle Time Out (in minutes) to define a
maximum period of time for which the login session is maintained
during inactivity. If the connection is inactive for longer than the
maximum idle time, it will perform system logout, and you have to
log into the Web management system again. (Default: 10
minutes)
