I couldn't manage to change my game account password by any way.
The in-game command simply don't works for me. Either I get the message "Invalid old password" or "New passwords do not match". Maybe I'm doing something wrong.
I tried both:
.account password #"oldpassword" #"newpassword" #"newpassword"
.account password #old "oldpassword" #new "newpassword" #new "newpassword"
And the Control Panel method didn't work too. I get the e-mail needed, but the two link options in it just redirects me to the Control Panel main page, so...
I also don't own any device that supports two factor authentication, so at this moment I really don't have any way to protect my account.
Please, give me some enlightenment here.
