title: How to remove stored keychain details from amazon iOS cognito SDK
body: <p>I am using <a href="https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoAuth-Sample" rel="nofollow noreferrer">CognitoAuth Sample</a> to implement sign-in and sign-out using AWS iOS SDK. </p>
  
  <p>I have a signout button inside my app. When I click the button I need to clear the keychain details instead of calling the signout block and showing the safari view controller. Is there any way to do so? The only thing I could see to do was using the signout block, but I don't want this.</p>
