If you're referring to your WiFi password, you can do so in the WiFi settings.
Click on the following link and use "admin", without the quotes, as the password. http://192.168.42.1/login.htm
You can then change the password for 2.4Ghz and/or 5Ghz radio on that page. Just change the password and click "Save Settings." Keep in mind that, if you're connected to the radio that you are changing the password for, you'll be kicked off, and you'll have to enter the new password in your device to reconnect. Because of this, it's best to change the password(s) with a LAN cable connected device.
If the password you're referring to is the password to enter the WiFi settings (admin), click on the same link, enter "admin" as the password, then click on "Administration" and "Password Settings". There you can change the administrative password.
The following link has a foldout that contains helpful info for the HT2000W, as well (including how to change the passwords). It's good to download and keep on hand.
