On the other hand, it's not hard to generate a second SSH keypair and register
it with your Launchpad account. That's what I'd do in this situation.
You can also delete the launchpad_username line from your bazaar.conf, which
should make lp: URLs resolve to HTTP rather than bzr+ssh automatically; i.e. if
you don't have an SSH key on a machine, don't use "bzr launchpad-login".
This is the launchpad-users mailing list archive — see also the general help for Launchpad.net mailing lists.
