TeamViewer, one of the most popular remote access programs, does not offer a built-in system for two-factor authentication. When TeamViewer is launched, it generates a short password and receives from the server a short number for full access to the current computer. How dangerous is this? Is there a possibility that someone could connect to a corporate computer again when no one is present?
Rohos Logon Key offers a way to protect TeamViewer sessions using an additional one-time password, thereby implementing two-factor authentication with a TeamViewer password as well as a one-time Google Authenticator password.
Advantages of protecting your system with two-factor authentication:
- Uses a one-time password that can only be used once;
- An unused one-time password will expire and become invalid after 5 minutes;
- No need to provide the remote party your Windows user account password;
- When a new TeamViewer session is started, Rohos Logon Key automatically locks the desktop to ask for two-factor authentication (experimental feature of the beta version);
- Two-factor authentication can be used only for TeamViewer sessions (experimental)
