Inability to log in
I have played this game (on windows and on mac) through the steam client for quite some time now. I have greatly enjoyed the game on all platforms thus far. In all my playing and work I have recently been able to rise all the way to vanguard and obtain 5* weapons and equipment. I just got a new computer and am running linux on it. I understand that SK does run fine in linux natively with no problems; my problem is I do not know how to log into my old account. It was created on steam and I understand there used to be workarounds, for example logging into facebook, which is now impossible. Is there anyway to find out my username and password to log into the vanilla(non-steam) client? If not is there anyway my account could be unlinked from steam. I greatly enjoy this game and would love to keep doing so, it would just be a shame to start from scratch. Thank you for your time and any help would be greatly appreciated!

There should be an option to log in using your steam account. If not, download steam, reinstall through steam and recheck.
There will be a box asking to login using your steam account, since your account is linked to steam everything should go smoothly.
And no, there isn't a way to unlink your account from steam
