I had so much trouble figuring out how you post a question on the Teamviewer Community. I have been using non-commercial Teamviewer for personal use with success for about a year to connect to a computer from NY to NC. Up to version 12, our passwords have always have always consisted of 4 numbers. After downloading and installing, Teamviewer 12, we were assigned passwords consisting of BOTH numbers and small letters. Did we download our Teamviewer 12 version from a hijacked site? I am very concerned about Internet security and the potential of hackers stealing personal information, and I thought it odd to receive passwords in a different format. Are we still secure?
