Dear Square Enix, Whoever told you that lobby errors should send back to desktop lied
Dear Square Enix.
Lobby errors happen. They shouldn't, but they do.
That said, whoever told you that lobby errors should send us back to desktop, forcing us to re-insert our password and one time password, lied to you.
That's the stupidest idea I could think at the moment, and I urge you to change it ASAP.
Ideally, your users should never be forced to insert their password more than once per session, no matter their connection status.
