You can use `AuthenticatorService` to access functions that lets you trigger transitions to the authenticator. Please see [Full API](#full-api) to see all supported transition functions. Any invalid transitions (e.g. `signUp` directly to `authenticated`) will be ignored.

```html{3}
<ng-container *ngIf="!!authenticator.user">
  <h2>Welcome, {{ authenticator.user.username }}!</h2>
  <button (click)="authenticator.signOut()">Sign Out</button>
</ng-container>
```
