# Enable Secure Authentication

To enable a global requirement for MiNET devices to be authenticated before connecting to the ICP:

1. On the MBG main page, click the System tab and click Settings.

2. Under MiNet Options, select the Restrict MiNet devices check box.

3. Click Save. Only MiNet devices that are configured on the MBG server will be able to connect.

Note: SIP devices are always authenticated. Accordingly, they must be added to the MBG server before connecting to the ICP.
