• Change the password. Use a password that’s not easy to guess and that consists of 
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an 
earlier working configuration may be useful if the device becomes unstable or even 
crashes. If you forget your password, you will have to reset the ZyXEL Device to its 
factory default settings. If you backed up an earlier configuration file, you would not have 
to totally re-configure the ZyXEL Device. You could simply restore your last 
configuration.
