Once on audioeye.com, you should see a "login" button in the upper right. Simply click that button and enter your username and password to login to your portal. From within the portal you will be able to access the dashboard for each site on your account.
We are in the progress of migrating some users over to our new portal experience. If your user account is still on the legacy experience you will automatically be redirected to another login page and asked to re-enter your details.
