+# Kerberos
+The configuration for Kerberos authentication will allow users to access ADF applications by entering their credentials only once when logging into their Windows environment.
+
+To enable Kerberos SSO and bypass the normal login, set the `withCredentials` property to `true` in the `auth` section of the `app.config.json`:
+
+```json
+{
+  "auth": {
+    "withCredentials": "true"
+  }
+}
+```
+
+**Note**: You don't need to use the [login component](../../docs/core/components/login.component.md) and [logout directive](../../docs/core/directives/logout.directive.md) in your app when using Kerberos.
