What is the best way to hide the sign out button if a user is not logged in?

On the login page the sign out button is visible before the user even logs in. The 'condition for visibility' doesn't appear to give me any options to hide it based on anything useful.   Any pointers of suggestions would be great.

You should be able to do this by basing the visibility on user Roles. Make sure your anonymous user role is unchecked
