Community profile ssh keys not making it to git

I'm trying to get a new machine set up for PostgreSQL development. On
the main PostgreSQL web site I got to "Your account", "Profile" and
add a line with a new key to the "SSH key" field, and it doesn't seem
to propegate to where it is used for git operations (based on the
fact that it's prompting for a password when I try to clone). Have I
forgotten how to do this, or is something broken on the servers?
