the weird thing is, you are the first one that asks this in all these years..
So there is not really one.
The thing is a bit that you don't really are logged in at the server, you constantly send over the authentication header and we are always checking that when you do a request..
You can create a case so we can add this (we need to see how a logout works with this, because we can't directly just delete that header i think)
hmm that can be a bit tricky i see now
