You can use `AuthenticatorService` to access `route` string that represents the current `authState`. They can be one of:

- `idle`
- `setup`
- `signIn`
- `signUp`
- `confirmSignIn`
- `confirmSignUp`
- `setupTOTP`
- `forceNewPassword`
- `resetPassword`
- `confirmResetPassword`
- `verifyUser`
- `confirmVerifyUser`
- `signOut`
- `authenticated`

```html
<!-- Only render this if there's an authenticated user -->
<ng-container *ngIf="authenticator.route === 'authenticated'">
  Welcome back!
</ng-container>

<!-- Render sign-in screen otherwise with authenticator -->
<ng-container *ngIf="authenticator.route !== 'authenticated'">
  <amplify-authenticator></amplify-authenticator>
</ng-container>
```

### Authentication Check

If you just need to check if you're authenticated or not, you can use the more straightforward `AuthenticatorService` to access the `authStatus` string. The `authStatus` string can represent the following states:

- `configuring`
- `authenticated`
- `unauthenticated`

> The `configuring` state only occurs when the `Authenticator` is first loading.

```html
<!-- Render loading if authStatus is still configuring  -->
<ng-container *ngIf="authenticator.authStatus === 'configuring'">
  Loading...
</ng-container>

<!-- Only render this if there's an authenticated user -->
<ng-container *ngIf="authenticator.authStatus === 'authenticated'">
  Welcome back!
</ng-container>

<!-- Render sign-in screen otherwise with authenticator -->
<ng-container *ngIf="authenticator.authStatus !== 'authenticated'">
  <amplify-authenticator></amplify-authenticator>
</ng-container>
```
