SMS OTP Authentication for Coin Withdrawals (Application)

Modified on Fri, 22 Dec 2023 at 04:05 PM

You can turn on an SMS OTP Authentication (to receive an OTP via SMS) to enhance the security of your digital asset withdrawals from your Bitkub account on our website and application. This function will allow you to use an SMS OTP together with 2FA authentication. Moreover, Bitkub also provides you with a Security Questions function in case of suspicious withdrawal requests. In the future, Bitkub will implement both functions, SMS OTP and Security Questions, for other activities further than coin withdrawals.

* You are required to verify your phone number that is bound to your Bitkub account before activating an SMS OTP function.
For new users, you can find more information about mobile number verification here.

  • Enabling OTP for coin withdrawals will affect the use of the Trust Address. You will need to enter both the OTP and 2FA codes each time before you save a new Trust Address. You can learn more from > Here
  • You are not able to deactivate 2FA and use only SMS OTP for coin withdrawals. Once SMS OTP has been activated, you will need both 2FA and SMS OTP when you withdraw coins.
