I use a password manager. I also store my password offline in a text file. I can log into the game with my password, but I cannot log into the forums. UNLESS, if I log into the forums using an Ubuntu box. Every browser I have in Windows - Firefox, Chrome, Opera, IE, Edge - gives me the same "password incorrect" message, despite that password working with the game itself. If I boot into Ubuntu, however, I can then log into the forums using the same password that was rejected under Windows.
What the...? Please help!
