Security key redirection enables the use of security keys through a TeamViewer session.
A security key plugged into the local computer can be recognized by the remote computer and used as if it were plugged directly into that computer, e.g., for web authentication, Windows logon, or running a task with elevated privileges.
⚠To ensure that the security key redirection works well, please note:
- The LAN mode should be deactivated on the remote side.
- There isn't an active RDP session on the remote side.
- 📌Note: If there has been an active RDP session at any time during a remote connection, the connection has to be restarted.
- The deployment process (MSI and EXE) will automatically remove the existing driver entirely without user input if it detects that the system is below Windows 10 or is a 32Bit system.
This article applies to customers with a TeamViewer Tensor license using Windows OS 8.1 and higher.
While the most familiar form of Two-Factor Authentication is a one-time password texted to your phone, the most secure version is a physical security key that serves this purpose instead.
When an account is protected with a security key, nobody can gain access without having both your password and physical access to your security key.
To use security key redirection:
- a TeamViewer Tensor license is required;
- TeamViewer Host or full version must be installed on the remote side; and
- the TeamViewer Virtual Security Key Driver must be installed on the remote computer.
📌Note: Some keys might require the installation of a mini driver on the remote machine. Please check the documentation of the key you intend to use.
