We use your steam ID for our authentication. The steam sign in window is steam's official third party sign in portal; we don't receive any of your login details as that is all handled securely by steam. Feel free to check the web request transmission source if you're not sure, but I can tell you that this is not malicious, and thousands of users have signed in with no issues.Why do you require users to resign in to Steam through your launcher? Sorry, I'm only trusting Steam with my Steam credentials. Once this changes, I'd love to try your mod, but as it stands now, this is totally insecure.
We do not plan to remove steam authentication.
