Not necessarily. A player can display an application-specific identifier, a device key or a value labelled MAC for its own activation system. Do not assume it is the hardware network address or that changing network settings will change it. Follow the publisher’s documented activation process.
Read the identifier’s purpose
An activation screen can pair software use with a particular installation or device. That is separate from the streaming-account username. Save the app name and the exact label of the identifier when asking support which value they require.
Share it only where necessary
Device identifiers may be relevant to account activation and should not be posted publicly as decoration in a review. Crop them from screenshots used for general troubleshooting. A QR code beside the identifier may encode the same private information.
Plan before replacing hardware
Moving to a new device can create a different identifier, and software licence transfer rules vary. Ask the publisher or seller about transfer before deleting the old setup. A new network adapter or factory reset can affect some identity schemes, but the behaviour is application-specific.
