# Access settings

The Theme settings described below apply to Parallels Client for all available platforms.

* **Override authentication domain**: Allows you to specify a domain name that will be passed to Parallels Client, so users don't have to enter it manually. This setting overrides the domain name setting in **Connection** > **Authentication**. For more information, see [**Allowing users to change domain password**](/landing/ras-admin-guide/v19-en-us/parallels-ras-19-administrators-guide/connection-and-authentication-settings/allowing-users-to-change-domain-password.md).
* **Limit access to this Theme to members of these Active Directory groups:** If this option is cleared, any Parallels RAS user can access the Theme if they know its URL. To limit access to a particular group (or groups), select this option and then click **Tasks** > **Add** (or click the **\[+]** icon) and select the desired group(s).
* **MFA provider:** Select an MFA provider for the Theme.
* **(Default theme only) Allow gateway tunneling connections**: Allow gateway tunneling connections for the deafult theme.
