How can i know if my account it's linked to Oirigin or EA account
Because i acces to the swtor launcher with another username and pass but in the registration i've used the same email
Unfortunately there is no way to know from your account if they are linked. In order to verify if they are linked, you would need to call SWTOR Customer Service as per this guide here and they can not only verify that your account is linked but which EA account it is linked to.
