You can use the eqemulator.net login. Just have friends create an account here, and make some login server (LS) accounts.
or
You can use Minlogin. This way you can keep your server private, however, Minilogin uses authentication by IP address. So only one account / computer practically.
You can search Minilogin in the forums here, or see the wiki on the main page...
