ASP.Net Identity sign-out all sessions

How do you sign-out all sessions with ASP.NET Identity?
Lets say you are signed-in from two different browser with the same user. When the user signs-out from one browser, the session of the other browser should be invalidated as well.
(I need this to invalided all sessions of a user on password change.)

You can sign-out the current session with ASP.Net Identity with the following code.

var AutheticationManager = HttpContext.GetOwinContext().Authentication;
AuthenticationManager.SignOut();

This will not sign-out all sessions of a user.

Edit:
The idea with the session was a good starting point. I solved the problem and wrote a blog post in case you have the same problem.

Method 1

You can achieve this by adding a newly created session from the Global.asax in a list.

Iterate afterwards to compare the user and SignOut the user’s sessions.

protected void Session_Start(object sender, EventArgs e)
{
    MyGlobalObject.Sessions.Add(HttpContext.GetOwinContext().Authentication);
}

And later, in the signout event:

private void SignoutAll()
{
    foreach (var authenticationManager in MyGlobalObject.Sessions)
    {
        authenticationManager.SignOut();
    }
}
