I just tried to log in and three or four times in a row I was told it was thew wrong password every time. I then tried to log in directly to my account on battle.net and it worked this time. No suspicious login adresses, no password change, no emails. After that I was able to log into the game. Scary.
One odd thing is that I looked at my password to see if it had been changed. I see we must type in the old password in order to change it. But the old password is not even the current one, it’s the one before that.
I just had this happen to me. My bnet was already logged in, I was already in-game. I was changing realms when I got a message saying my PW wasn’t recognized. (Not the exact wording). Shut down the game, I tried about 5 more times, even got a queue of 1 before it repeated the same PW message.
I am back in the game now, I didn’t physically change my PW or type it in, I just kept trying & it finally let me back on. I forget the error code it gave me & I did not screenshot it (wish I had).
