How about not having to input the password at all? If that's
acceptable then you can use a public/private key pair to enable
password-less logins. Here's the script I use when creating new key
pairs. You'll want to edit the variables at the top to your taste
before pasting the contents into a console on your (local) machine.
Once you have your public ssh key ('id_rsa.pub' in my script)
installed on the remote server you will be able to log in without a
password using ssh (and rsync with the -e "ssh" bits). Remember to
never share your private key ('id_rsa' in my script) - 'Keep it
secret, keep it safe.'
