Locking as I can’t see this discussion going anywhere constructive and the op is a long way from the guidelines for balance threads

Funny because FAF has stopped caring about which PC you use for over a year now. There is no "new security", you could say there is less than before. The only thing that you need is valid Steam link that is linked to exactly one account. Then you can use that account anywhere. Btw why should anybody try to help you if you didnt even take the time to properly describe the problem your are having.
