On WindowsPC

# in command window, if ssh key not exists,
ssh-keygen -t rsa -b 4096

copy public key file 'id_rsa.pub' to raspberrypi's 'git'user's home '~/' with WinSCP or sftp tools

# if authorized_keys file does not exist
cat id_rsa.pub > ~/.ssh/authorized_keys

Host rpipi
    HostName 70.1.1.10
    Port 22
    User pi
    IdentityFile ~/.ssh/id_rsa

Host rpigit
    HostName 70.1.1.10

TADA~! you can make ssh connections passwordless, even in git remote connections.

C:\Users\user1>git clone ssh://git@rpigit:/home/git/git_repo/first.git first.git
Cloning into 'first.git'...
warning: You appear to have cloned an empty repository.
