I'm currently getting an "ID or Password is incorrect" error when attempting login via the FFXIV launcher.
I have confirmed the ability to successfully login to the following utilizing the same credentials:
FFXIV Forums
FFXIV Lodestone
Mogstation
Currently the only issue seems to be with login via the launcher at this time and any assistance would be appreciated.
EDIT: Issue seems to have resolved itself after performing a computer reboot and repair of the launcher.
