I just did a manual install and tried to login, but was unable to do so using domain.com/login. I got a 404 error. When I used domain.com/wp-admin, no issues. Did I do something wrong or forget to do something?
If you have enabled permalinks it should work though.
You can and should localize it if you use other languages:
/login is not a valid url unless you have edited your .htaccess to redirect it correctly.
perhaps you are looking for /wp-login.php
