How does connecting to a contact work?

[thompson004]

Hi!

I wanted to ask a question: If I add a contact via Teamviewer and said contact is logged into multiple Teamviewer modules, how does my Teamviewer module decide which device to connect to? (If there is more than one module running at the moment)
Also, if I send a chat message, does my contact receive it on all his active modules?

I know that there is the confirmation prompt, so do I connect with the module where my partner accepts the prompt? This would explain it, but there would be another way: Connecting via password. What if my partner uses the same personal password on two or more of his modules? How does my module decide which device to connect to, if I use "Connect with password" and use the password he uses on both machines?

Thank you!
