Also called: Device MAC, Hardware address.
Every network-connected device has a MAC address. IPTV uses it on MAG boxes, which are activated by MAC, and in some Smart TV apps that show a MAC address and device key on screen so the provider or app website can attach your playlist to that device.
You can usually find it in the device’s network or system settings, or on a label underneath the box. Sharing it with your provider only lets them link the subscription to that device — it gives no access to your network.
How does MAC address apply to SynexaTV?
SynexaTV support can activate a MAG box or a MAC-based TV app from the MAC address you send on WhatsApp or Telegram.
