Authentification in gitlab from win client

I have gitlab on ubuntu + win GIT. I login to win with my domain account

I firstly login to gitlab web inteface and created first project
When I try to make ’ git clone’ at win, I didn’t ask password. Why? Even thou when I push changes, at Activity page I see that changes was made by Administrator. But when I open project page? I see, that ‘some user’ has commited.
‘some user’ - it was my local git config througth 'git config --global “some user”
