Cognito Federated user logout

Question

For cognito user - Using Amplify I was able to login using

```
await Auth.signIn(this.email, this.password);
```

And logout using:

```
Auth.signOut();
```

For federated user - Using Amplify I was able to login using

```
await Auth.federatedSignIn({ customProvider: 'customProviderName' });
```

But logout doesnt support using:

```
Auth.signOut();
```

How can I signout federated user, so that when I try to login again, it ask my permission to login ?

Answer

According to the documentation ([here](https://docs.aws.amazon.com/cognito/latest/developerguide/logout-endpoint.html)), you need to either redirect the user to the Cognito endpoint: 
GET https://mydomain.auth.us-east-1.amazoncognito.com/logout or perform the GET yourself and then redirect to the correct sign-in location. The former is going to be easier.
