Better sending them a personal message instead of posting here as all the post on here might not be checked and if checked then it may take longer time than usual which may make you more boring.
Your reply is several days late and the mods have already told him to wait until Ethan replies on the site. Also if you didn't notice the post above you he already said that his problem was fixed.
Perhaps this problem should be better overcome if Ethan has more partners to solve for the user.
Assuming that the worst case scenario happened with Ethan, maybe the players would suffer huge damage.
Depends, if a lot of users lose their 2fa they could assign someone.
