Basically since the big patch 2 weeks ago (that changed the launcher to the PoF design), the 2FA is kinda broken. It happens quite often that it rejects a code and then, after you enter the same code again, it gets accepted.

This might be caused by ANet using a ridiculously narrow time-window for valid codes (I know that the RFC recommends one time-step – but right now it feels like ANet uses zero steps so a code transmitted a second too early/late will fail instead of still being valid).

And no, its not related to the clock of my local PC (its synchronized with the atomic clock of the PTB (Physikalisch-Technische Bundesanstalt -> ptbtime1.ptb.de) here in germany and before that it was synchronized with the official windows-timeservers (time.windows.com) -> it failed in both cases – so i’m pretty sure that i’m sending the right code.
