#### To set the default realm

The default realm is the realm that the Application Server uses for authentication and authorization if an application's deployment descriptor does not specify a realm.

1. Expand the Configurations node.

2. Select the instance to configure:

   - To configure a particular instance, expand the instance's config node. For example, the default instance, `server`, expand the `server-config` node.

   - To configure the default settings for all instances, expand the `default-config` node.

3. Select the Security node.

   The Security page displays.

4. In the Default Realm field, pick the desired realm from the drop-down list.

5. Click Save to save the changes or Load Defaults to delete changes and restore the Application Server default values.

6. Restart the server if Restart Required displays in the console.
