SMS OTP Authentication for Coin Withdrawals (Website)

Modified on Thu, 28 Dec 2023 at 12:21 PM

You can turn on an SMS OTP Authentication (to receive an OTP via SMS) to upgrade 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.

 

For application, please refer to > click here.

* You are required to verify your mobile 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.
