I know, but you can’t use your characters from your PS4, on your PC 
I think you’re misunderstanding something, please let me explain
When you start boundless, either PC or PS4, it asks for your boundless account login. If you havent changed platforms in a while, you likely haven’t seen it in years. When i played on PS4, i made an account for this and used it for PS4. I now installed boundless on PC and without creating an account, i used my old boundless account credentials to log in. This worked. Obviously i don’t see my PS4 characters, as i already knew you can’t share characters (and thus the items on them) across platforms. But it’s still the same boundless account as i used on PS4.
The question is, if my friend logs in on PS4 with my account, will he log me out of my PC session, as it’s also using the same boundless account
