# [Login Dialog component](../../../lib/core/src/lib/login/components/login-dialog.component.ts "Defined in login-dialog.component.ts")
Allows a user to perform a login via a dialog.
## Details
The [Login Dialog component](login-dialog.component.md) allows you to perform a login via a dialog.
### Showing the dialog
Unlike most components, the [Login Dialog Component](login-dialog.component.md) is typically shown in a dialog box
rather than the main page and you are responsible for opening the dialog yourself. You can use the
[Angular Material Dialog](https://material.angular.io/components/dialog/overview) for this,
as shown in the usage example. ADF provides the [`LoginDialogComponentData`](../../../lib/core/src/lib/login/components/login-dialog-component-data.interface.ts) interface
to work with the Dialog's
[data option](https://material.angular.io/components/dialog/overview#sharing-data-with-the-dialog-component-):
```ts
export interface LoginDialogComponentData {
title: string;
actionName?: string;
logged: Subject<any>;
}
```
The properties are described in the table below:
| Name | Type | Default value | Description |
| ---- | ---- | ------------- | ----------- |
| title | `string` | "" | Dialog title |
| actionName | `string` | "" | Text to appear on the dialog's main action button ("Login", "Access", etc) |
| logged | [`EventEmitter`](https://angular.io/api/core/EventEmitter)`<any>` | | Event emitted when the login succeeds. |
If you don't want to manage the dialog yourself then it is easier to use the
[Login Dialog Panel component](login-dialog-panel.component.md), or the
methods of the [Login Dialog service](../services/login-dialog.service.md), which create
the dialog for you.
### Usage example
```ts
import { MatDialog } from '@angular/material/dialog';
import { LoginDialogComponentData, LoginDialogComponent} from '@adf/core'
import { Subject } from 'rxjs/Subject';
...
constructor(dialog: MatDialog ... ) {}
openLoginDialog() {
data: LoginDialogComponentData = {
title: "Perform a Login",
actionName: "Access",
logged: new Subject<any>()
};
this.dialog.open(
LoginDialogComponent,
{
data, panelClass: 'adf-login-dialog',
width: '630px'
}
);
data.logged.subscribe(() => {
// Action after being logged in...
},
(error)=>{
//your error handling
},
()=>{
//action called when an action or cancel is clicked on the dialog
this.dialog.closeAll();
});
}
```
All the results will be streamed to the logged [subject](http://reactivex.io/rxjs/manual/overview.html#subject) present in the [`LoginDialogComponentData`](../../../lib/core/src/lib/login/components/login-dialog-component-data.interface.ts) object passed to the dialog.
When the dialog action is selected by clicking, the `data.logged` stream will be completed.
