One question about the complimentary Cartel Coin for the Security key.
"How this change affect this? If I change my security key, i will lose them for one month?"
Edit: another question.
"This one time is a bit annoying, you will provide more physical security keys? They are currently out of stock..."
So long as you reconnect an authenticator before the following months stipend the service is uninterrupted.
To those who are complaining about not being able to get a physical authenticator I suggest mobile authenticator

I hope this helps.
