Use of two machines, video

Hello everybody,

I assist my mother via TeamViewer for her use of Windows.

For more simplicity, I connected to her machine with my account. So, my account is connected to both machines.

This works OK, except a time period with suspicion of commercial use, but this seems over.

Recently, we wanted to use video communication between both machines. That works, but my photograph appears for both machines, and that can be confusing.

Maybe the best is to create a TeamViewer account for my mother, or can I put several photographs in my account and choose one for each machine ?
