TeamViewer: Using Windows login on remote computer

Problem

By default, you need to know the password generated by TeamViewer on the remote computer to connect to it. But, the problem is that TeamViewer generates a different password everytime it is re-started. Instead, it would be convenient to just login into the remote computer using the Windows login credentials on that computer.

Solution

To be able to login using the Windows credentials of the remote computer, you first need to enable this on the remote computer.

Open TeamViewer on the remote computer and choose Extras → Options. In Security → Rules for connecting to this computer → Windows logon, choose one of either Allowed for all users or Allowed for administrators only.

Back on your own computer, when you connect to the remote computer TeamViewer presents you with a TeamViewer authentication dialog. Choose Advanced here and for Authentication dropdown choose Windows. You should be able to login now into the remote computer using your Windows login credentials on that computer.

Tried with: TeamViewer 7.0.12313

  2. Allowing Windows logon – for any type of user – provides a TeamViewer hacker direct access to attack your windows credentials directly. They could easily launch a script that could try thousands of possible passwords a second. If you change the setting to “not allowed”, and your computer is configured to be at the login/lock screen whenever you are not using it, the attacker is forced to enter each Windows password manually in order to gain access.

    TL;DR: having the “Windows Logon” setting set to anything other than “not allowed” is a serious weakening of TeamViewer security.

      Actually as long as you are setting a secure password, which should be standard, then it shouldn’t matter all that much. Especially when there are far more statistically successful ways to gain entry.

      For instance:

      Even if I set this to “Allow for all users” and someone attempts to run a “Script”, also known as, a “Brute Force Attack”, “Common Word Attack”, or “Dictionary Attack”. If I have a password such as “this is hard”, it would still take around 2,500 years to successfully gain entry into the system through Teamviewer.
