Unable to authenticate to SSH host

I am rtryin to upload test code to my "junk/test-yacs"

I am using windows XP and I have BZR installed.

command line:

>bzr launchpad-login phpwalter
/ 0kB @ 0kB/s

>bzr push lp:~phpwalter/+junk/test-yacs
Adding ssh-rsa host key for bazaar.launchpad.net: 9D383A63B1D56FC4446753492EEEFC
89
SSH <email address hidden> password: [I enter PW]
Authentication type (password) not permitted.
bzr: ERROR: Connection error: Unable to authenticate to SSH host as phpwalter@ba
zaar.launchpad.net Bad authentication type (allowed_types=['publickey'])

So I guess the question is how to I get BZR to know about my public key?

BTW: I am not finding LaunchPad the easier system to use. As you can see, I opened my project about 8 months ago and as of yet have had the hours to devote to set this up.

I'm writing you this note after a bout 2 hours of trying.

Hope you can help.
