i can also confirm what the post above me said. i am using the authenticator, and when going through the normal login process, i was unable to log in. the error message claims my password or username/email is wrong, but i am quite sure the authenticator is the problem, because if i intentionally enter a wrong password, i am not even allowed to enter the authenticator-code. in my case, i was allowed to enter the authenticator-code, and afterwards i got the wrong-data message.
but, when i tried to add a reply to this thread, the website asked me to log in, and i was able to log in without problems.
