Step 5: Add passwords to the configuration
After enabling Private Pre-Shared Keys, a modal appears where you can add passwords to a given network. Choose the default network, but you could add passwords for a specific network that is linked to a VLAN. For example, you can add a password “iotdevicespassword” and link it to the iot VLAN. This way, the device that uses this password will be isolated.
