How do I create a new WiFi password for home?

During the initial setup, the first password created is a Home zone password, although you can add more to the WPA2 SSID. Local network access to devices connected to your network in the Home zone can be selectively shared with devices connecting with a Guest zone password.  

Note: Multiple Passwords are not supported for the WPA3 SSID.   

1. Open the Menu & Settings page and tap on the Adapt option.
2. On the WPA2 SSID, tap on the Home button. 
3. While on the Home settings page, tap on New home password. 
4. Enter your new password.
5. Tap on the Add to save.
