# Guest OS Credentials

In guest OS credentials settings, you can set an account that will be used to collect data from the guest OS of Windows and Linux-based VMs.

To access **Guest OS Credentials** settings:

1. Open Veeam ONE Client.

   For details, see [Accessing Veeam ONE Components](access.md).

2. In the main menu, click **Settings** > **Server Settings**.

   Alternatively, press `[CTRL + S]` on the keyboard.

3. In the **Server Settings** window, open the **Guest OS Credentials** tab.
4. Specify guest OS credentials:

   1. In the **Microsoft Windows** section, select credentials of an account that will be used to collect data from the guest OS of Windows-based VMs. To create a new credentials record, click **Add**.
   2. In the **Linux** section, select credentials of an account that will be used to collect data from the guest OS of Linux-based VMs. To create a new credentials record, click **Add** and select **Standard account** or **Linux private key**.

      In the **SSH Port** field, change the default connection port if required.

      To disable fingerprint validation for Linux VMs, select **Skip fingerprint check**.

   To access credentials manager, click the **Manage Credentials** link. For details on working with credentials, see [Security](credentials_manager.md).
