Change Password
For security, the gateway has its own user names and passwords. NETGEAR recommends
that you change the default passwords to more secure passwords. The ideal passwords
should contain no dictionary words from any language, and should be a mixture of both upper
and lower case letters, numbers, and symbols. Your passwords can be up to 30 characters.

To change the password, enter the new password twice.

After changing the password, you are required to log in again to continue the configuration. If
you have backed up the gateway settings previously, you should do a new backup so that the
saved settings file includes the new password.
