Sorry if you're already doing this, but to use the emergency removal password you have to go a special page, you can't log in with it. The special page is located at:

https://secure.square-enix.com/accou...vc/coercioncan

From there you can fill in the relevant fields to remove the one-time-password from your account so you can ignore it when asked later until you re-add it.

Again I apologise if you were already doing this, just wanted to make sure you were aware of this.
