[2020] [PC] [Ubisoft Account]Ubisoft Account

I can't play For Honor, the reason is that I have a ubisoft account that I can't recover anymore, I don't know it anymore, but I have the game, it also appears on steam, from August 23, 2018. Something can be done about it, if you can or how can you help me? I leave below a screenshot with proof that I have the game.
