first of all let me say: nice plugin.
so here's the issue:
1. i tried to add another user, but when i tried to login with the user name it does not show the otp password, which make the newly created user cannot login.
2. i have to disable the login box before the user can login to generate the otp.
I'm trying to read the source code now, but I hope there's an easier work around.
If you wouldn't mind giving me pointer on how to solve this issue i don't mind doing the programming and update it here.
