+# Angular UI: Current User
+
+Current user information store in Config State.
+
+### How to Get a Current User Information Configuration
+
+You can use the `getOne` or `getOne$` method of `ConfigStateService` to get a specific configuration property. For that, the property name should be passed to the method as parameter.
+
+```js
+// this.config is instance of ConfigStateService
+
+const currentUser = this.config.getOne("currentUser");
+
+// or
+this.config.getOne$("currentUser").subscribe(currentUser => {
+   // use currentUser here
+})
+```
+ 
+> See the [ConfigStateService](./Config-State-Service) for more information.
