I used TeamViewer a year or so ago and I thought the default installation was the the Client/Pal you are helping had to let you in (accept you the Server/Controller).
The other day I set a pal up with teamviewer and he said that I just connected and that he had no warning that I was connecting.
Obviously we exchanged ID and Password over the phone.
He should have been warned that I was connecting and been given the option to refuse.
Where is the option to stop auto/unattended access?
Thanks.
