Since ETN is traded on kucoin there are some annoyances recently added to kucoin.

You must add 3 answers to 3 security questions on kucoin.

Then, when you withdraw your coins from kucoin you have to:
- input 2 factor authentication code
- input an answer for one of 3 security questions
- read your email and confirm the withdraw.

This kind of sucks, in order to do one thing you must do 4 other things (the three of them I've mentioned and of course the 4th is to login to kucoin.

I never saw anywhere else such thing. Everywhere it is two factor auth: login and then choose between: 2fa, email confirmation or a pin code.
