@nikaido_03 Hey there! I am sorry to hear that you are receiving an authentication error when trying to play For Honor. To help with this I recommend trying logging out of both Steam and Ubisoft Connect, closing the launcher, then relaunching and logging back in with the correct accounts to test if that helps you.

If it does not, please create a support ticket with our team with your Steam proof of purchase and your Steam ID along with your launcher logs and our teams will be happy to take a look further!
