+# Login Dialog service
+
+Manages login dialogs.
+
+## Methods
+
+-   **openLogin**(actionName: `string`, title: `string`): [`Observable`](http://reactivex.io/documentation/observable.html)`<string>`<br/>
+    Opens a login dialog.
+    -   _actionName:_ `string`  - Text to show in the main action button
+    -   _title:_ `string`  - Title for the login dialog
+    -   **Returns** [`Observable`](http://reactivex.io/documentation/observable.html)`<string>` - Confirmation of login from the dialog
+-   **close**(): `<void>`<br/>
+    Closes the currently open login dialog.
+
+## Details
+
+Use the methods of this service to manage login dialogs from code. As an alternative, you may
+find it easier to use the [Login dialog component](login-dialog.component.md) to display the
+dialog directly from HTML.
