Thanks for the quick fix. I did some testing if they have an access token in the browser, they would continue to be authorized, but once that's gone, they would become unauthorized (have to /login again)
So it seems reasonable as we can't revoke access_token

Great job!! All tests passed! I also tested an endpoint that need an admin to logged in and it worked!
