California IoT regulation
To comply with the regulation, when connecting to a new or factory reset unit, you will be required to enter a password for the administrator and there is no longer a default password. A password must be alphanumeric and be at least 8 characters in length. When upgrading the firmware, the existing usernames and password persist and will remain unchanged.
