### Command Line Installation

1. Download Twosense Installer MSI. The link will be provided by your Twosense account manager.
2. Open a Command Prompt or PowerShell (**as Administrator**), and navigate to the file path where the MSI file is located.
3. Enter the following command (replace with the appropriate MSI filename and parameters):\
   \
   `msiexec.exe /i TwosenseAuthenticator-x.y.z.msi /qn+ IKEY="[your key here]" SKEY="[your key here]" GROUPID="[your group id]"`\
   \\

   **Parameters:**

   * **IKEY**: Your integration key. (Required)
   * **SKEY**: Your secret key. (Required)
   * **GROUPID**: The group ID for the machine. (Optional)
   * **IGNORERDP**: Set to *1* to bypass Twosense when logging into the machine via RDP. If set to *0* or left unset, Twosense will operate normally during RDP login. (Optional)
   * **SKIPVALIDATION**: Set to *1* to bypass installation validations. If set to *0* or left unset, the installer will run its normal validation checks, which include verifying that the IKEY and SKEY are properly configured and validated. (Optional)

   **Notes**

   * The values for parameters `IKEY`, `SKEY`, and `GROUPID` are **case-sensitive**.
   * To disable showing the success/failure message post-installation, change the `/qn+` to `/qn`.
   * To enable logging add `/l*v twosense-installer-log.txt` to the end of the command. You can specify a different filename or path as needed.
4. Reboot after the installation has finished.

To check that the installation was successful:

* After rebooting the machine, log in as any user.
* Open the Twosense portal at <https://app.twosense.ai/login>.
