Pre-firmware 7.0 devices use password-based auth. The password is derived from the device serial number printed on the label, making it predictable for any physically identified unit. Firmware 7.0+ switched to cloud-token authentication via Enlighten credentials. CISA advisory ICSA-23-171-01 and CVE-2023-33869 document related issues.
