Can we get single sign on support for Steam and PlayStation versions like Xbox?

They said something about players already having an account to not participate in the Beta, since the way that your SE and Microsoft accounts will be link is irreversible and it could cause issue later on. I have a feeling the way that they are marrying to two accounts to allow the single sign on either is not allowed by other platforms for privacy sake or because it can cause account issues too easily.

Existing players can't take part in the open beta on Xbox as they're only making the free trial available on the Xbox Store, not the full game client. More importantly, linking your Square Enix account to a Microsoft account is permanent so they want to avoid people linking a XIV trial to their main/only Microsoft account. My assumption is that Microsoft are stricter about account linking and single sign on requirements than both Sony and Valve are.
