FINAL FANTASY XIV Online: How do I recover my old account?
Short answer
Suggested fix (unconfirmed): Contact Square Enix Customer Support to recover your account details. Do not try to register your CD key again on a new account, as keys can only be used once.
The problem
I tried playing this a few back but I couldn't login, I want to try again. Is there still issues with account recovery?
Suggested fix (unconfirmed): Report the guide to Steam support and direct your questions regarding plugin policy to Square Enix support. If you do not wish to use plugins, simply choose not to use them.
Suggested fix (unconfirmed): Ignore players using cosmetic mods and do not engage with them. Alternatively, disable third-party texturing tools to prevent custom client-side appearance modifications.
