Can't reset my password without a security key.
I played many years ago and thought I'd give it a go in 2020, but I've long ago lost my security key. I don't know the password to the account but when I go to reset it, it needs the security key. ...
If you dont know the password and dont have the security key , you need to call support so they can remove the key manually https://help.ea.com/en-us/help/star-wars/star-wars-the-old-republic/swtor-support/
