Are you using ssh-agent, and are SSH_AGENT_PID and SSH_AUTH_SOCK set
in your shell but not in Emacs?

I have written the ssh-agency package which tries to find the correct
values for those environment variables automatically. Originally it
was written for magit on w32 systems, but it turns out to be useful on
GNU systems as well. And it should be usable for vc-git, it's just a a
matter of arranging to have `ssh-agency-ensure' called before 'git
push' is run.

Or if you expect to get a password prompt every time, then I think
it's just that Emacs is not using a pty when running 'git push', which
causes git (or ssh?) to use ssh-askpass instead.
