No, you do not need to have your @breezeline.net login and password to use the Stream TV services on your box (Live TV, On Demand, Cloud DVR, etc.). However, you will need your @breezeline.net login for any additional cable channel apps you choose to download like HBO Max, ESPN, TBS, etc. if your video subscription includes those channels.
Do I need to have my @breezeline.net login and password to use my Stream TV Box?
