Comment 2 for bug 568106

I think this happens because when you authorize the OP to send your details to Launchpad, the OP stores that authorization and keep it valid for some time, so the next time you login the OP will send your account details without asking for your permission.

AFAIK, the only thing that Launchpad could do is to tell the OP to always require the user to *authenticate*, but I'm not sure that's what we want.
