You've probably noticed that we have disabled two-factor authentication for login. It has been replaced with 2FA for withdrawals. That is, when requesting a payment, you will see the same verification that until recently was for login.
If you want to return 2FA for login, you can do it yourself in your Account, section 2FA. You can also disable 2FA for withdrawal there, but we do not recommend doing this.
We wish you lot’s of profit and care of the safety of your funds.
