You should have gotten an email with your admin password after you installed wordpress. If you need your password resent you can go to your log in page and click forgot password and it will send password to your email, your log in is admin.
If you didn’t put in the correct email when you installed wordpress you can log in to your server, open your database in phpmyadmin, go to wp_users (provided you used wp_ as db prefix otherwise XXX_users) click browse tab and you will see your users along with the email address. If there is no email or it is wrong for admin click edit and change it. Then click GO (default is save when you click go). If you have to go this route and you change your email then you need to go to your login page again and click forgot password so that it sends you a new email to the corrected address with your password.
