Security is always the No.1 priority to all trading platforms since it accumulates a huge amount of users’ assets. 2FA login is an effective way to make sure the account is logged in by its real owner. However, if the user is confident that their device is 100% unhackable and safe, and there’s no need for a 2FA, they can go to Account, User Preference, then turn on the switch to Disable two factor authentication for login, which is switched off by default.
It’s worth mentioning that this switch-off is only working for log in. With regard to withdrawal, 2FA is still a mandatory step.
