I've tried to log into my account, it asked for my authenticator, I dont know what went wrong but it said "Invalid credentials". I've disabeled my authenticator and enabled it again, exactly the same problem. In my Google thing with "Apps with acces to the authenticator" it doesn't include anything related to Runescape.
I've searched some threads but they all keep saying the same things I've already done. Anyone has any idea's?
