Recommended Practices

To improve network security, the following guidelines are recommended when configuring
the gateway:
Set the password of the primary web user account (see
Accounts) to a unique, hard-to-hack string. Do not use the same password for several
devices as a single compromise may lead to others. Keep this password safe at all times
and change it frequently.
