Finding my soldiers orgin account?

[JBaubz]

So I can't seem to be able to find what orgin account my soldier is on? Its not on the current account i am asking the question on and this is the only one i know of. I had a 360, but I now am using a ps4. I have used the battlelog app, but i signed in through the qr code. Is there an easy way to find what my soldier's account is?
